Major addition: Local caching of project files.  When this is enabled, the project's root directory will be copied to the ~/rendercache directory on each selected computer, then the render path will be changed to refer to the new relative location.  This should considerably speed up rendering of very large files by allowing them to reside on local storage.  At the end of the render it should collect the rendered frames from each computer and place them in the shared render directory.

There have been some other misc fixes and rearrangements.  I've done some testing, but not a whole lot yet.  This should be considered a highly unstable release.
