The default plane configuration supports setting the plane color, but
this option is not currently exposed via the terrain importer. This PR
adds a ``color'' field to the terrain importer that is only used for
configuring a plane.

# Description

The `disable_contact_processing` flag inside the SimulationContext
causes confusion, as we were setting it to True in many environments,
but it should be False since we want PhysX to report the contacts.

This MR changes the default behavior now. It is always disabled (i.e. no
contact reporting), until a contact sensor is created. It makes sure
that the performance isn't hampered in situations where the user doesn't
want to create any contact sensors.

# Description

The previous fix in #1654 was checking if `effort_limits_sim` is None
instead of checking `cfg.effort_limits_sim` for explicit actuators. This
did NOT work as effort limits sim is a tensor that gets assigned the
value on initialization.

The new fix now adds an implicit/explicit model attribute to the
actuator model to ensure the right defaults are getting set. It moves
all the implicit actuator warning code to its class to keep the
articulation class cleaner.

We also revert the behavior of setting velocity limits for implicit
actuators to the state before #1509. Before that change, the parameter
`velocity_limit` was set in the configurations but not getting passed
through. The MR #1509 allowed these values to be set which caused many
of the assets to not train anymore or behave differently between
IsaacLab versions. We now revert this behavior with a warning. If users
want to set the limits, they should use the `effort_limit_sim` and
`velocity_limit_sim` quantities.

Fixes #1837

Currently, the WebRTC livestream is limited to connections within the
same local network. This change introduces the ability to set a public
IP address as an environment variable to allow connecting over the
Internet and allows for livestreaming remotely when using the pre-built
Isaac Lab container.

Note:
This may not fix the livestreaming issue when using pip or native
install of Isaac Lab, as it requires an updated version of the
livestream extension, which is only available through the docker image
at the moment. This will be fully fixed in the next version of Isaac
Sim.

Example: 

Run with `PUBLIC_IP=$(curl -s ifconfig.me) LIVESTREAM=2 ./isaaclab.sh -p
scripts/demos/quadrupeds.py` then connect using the [Isaac Sim WebRTC
Streaming
Client](https://docs.isaacsim.omniverse.nvidia.com/latest/installation/manual_livestream_clients.html#isaac-sim-short-webrtc-streaming-client).

`PUBLIC_IP` can also be set to a private IP address if connecting within
the same local network.

# Description

When reset_root_state_from_terrain is called from an EventTerm, we
cannot predict which env_ids will be targeted. To prevent program
crashes due to tensor size mismatches, this MR modifies the velocity
calculation to use only the specified env_ids instead of referencing all
environments.

Changes:
- Updated velocity calculation to use env_ids indexing for
default_root_state
- This ensures tensor dimensions match between default_root_state and
rand_samples

# Description

Previously, the ANYmal URDF importer example was setting the stiffness
and damping to new defaults (100.0 and 0.1 respectively). However, this
is undesirable as we want to import the asset with no stiffness and
damping (as we do effort control). This MR corrects the instructions to
convert ANYmal asset.

# Description
The pip command:
```
pip install isaacsim[all,extscache]==4.5.0 --extra-index-url https://pypi.nvidia.com
```
does not work because of the brackets and would give the following
error:
```
no matches found: isaacsim[all,extscache]==4.5.0
```
There exist two ways to fix this either by quoting:
```
pip install 'isaacsim[all,extscache]==4.5.0' --extra-index-url https://pypi.nvidia.com
```
or by escaping the brackets:
```
pip install isaacsim\[all,extscache\]==4.5.0 --extra-index-url https://pypi.nvidia.com
```

The "object" obs group in the Franka stacking environment contains the
absolute position of each of the cubes. At the moment they are being
returned as world positions which include the env offset if running
multiple envs in parallel, causing inconsistent position values.

Fixes:

Eliminates the environment offset from the cube positions in the
"object" obs group of the Franka stacking environment by subtracting out
the environment origin.

## Description

The drift in raycaster didn't update when reset. This MR now updates it
correctly:

before:
```python
self.drift[env_ids].uniform_(*self.cfg.drift_range)
```

now:
```python
self.drift[env_ids] = self.drift[env_ids].uniform_(*self.cfg.drift_range)
```

# Description

Since extensions are now added to the app files, they get automatically
reloaded when changes happen in the extension scripts. This feature is
most likely not useful for Isaac Lab development workflows. This change
disables the hot reload feature as it causes confusion and unnecessary
reloading of the modules.

Fixes #1779

# Description

This PR fixes the `xdg-open` command in the documentation that instructs
users on how to preview the documentation locally. Previously, the
command pointed to `docs/_build/html/index.html`, which is incorrect.
The correct path is now `docs/_build/current/index.html`.

# Description

Documentation only change to change spelling of Nvidia to NVIDIA and
update the EULA link.

# Description

This PR is linked to https://github.com/isaac-sim/IsaacLab/issues/1756. 
In short, with the recent deprecation of the `body_state_w` variable,
and then the removal of the deprecation, there are now 3 ways to get the
states from the `ArticulationData` class: `body_state_w`,
`body_com_state_w` and `body_link_state_w`. Commit
999c1e9a removed the deprecation,
removing any `write_root_com.*` and `write_root_link.*` calls and
therefore not updating the `body_com_state_w` and `body_link_state_w`
until the next physics step. This caused any use of the
`body_com_state_w` and `body_link_state_w` buffers to be 1 step behind
after an environment is reset.

Fixes #1762 

This PR updates the timestep of the `body_com_state_w` and
`body_link_state_w` buffers to -1 in the `write_root_pose_to_sim`
function in the `Articulation` class so that they update correctly. It
allows for use of all 3 buffers instead of only `body_state_w`.

# Description

Due to limitations from PyPI, all dependency packages have to be
published pip packages.
Unfortunately, RSL RL currently does not have a pip package, so we could
not include it into the Isaac Lab package.
This PR adds the instructions to install RSL RL separately from pip when
using pip installed Isaac Lab.
