Effect Files and Mesh Files

I’ve been working out some bugs that were related to the loading and saving of effect files.  I have to admit, when I was working on the effect system I didn’t do a lot of testing with file saving and loading.  However, I think I have all of the bugs worked out now.  I’ve also been updating the mesh file format.  It’s a lot more flexible, and still very extensible.  All of the new mesh file updates are also supported by the exporter.  For example, I added some basic support to the exporter for exporting patch meshes.  I’ll wait to refine this stuff later.  I have more important things to work out right now.
