Houdini Project Node

This node should be located in every working HIP file. Once user launched the Houdini from Houdini Launcher or Shotgun, this node should be created at first.

Changing the $ROOT for working root from Server to Local, so that user can cache the bgeo files to local. This is because it's not really efficiency to reading/writing cache files through the network. While done caching the files, user can sync the files to the render farm.

This node will also load the default setting for IFD node according to the project. This is because our studio will provide different setup for each project.
