Many minor cleanups in preparation for a beta release.
 - Removed VERSION.txt
 - Can't package a Linux binary Shoes unless crosscompile build
   because you can't expect the user's ruby to be /home/ccoupe/.rvm/...
   or depend on the recipients ruby to be --enable-load-relative
 - Can't install a crosscompiled build to ~/.shoes/federales - that's the
   installers job
 - tweaked the Shoes.desktop creation. Still not perfect.
 - deleted shoes.a after linking shoes main (for default builds)
 - fixed chipmunk to load in the Loose Shoes (default build)
 - Did I mention the default linux build is really small in size and
   doesn't have a lot of BS files that aren't duplicated (no additional copy
   of Ruby libs) and it can be put in ~/.shoes with a 'rake install'?
 - commented out the info messages. The default build for linux should display
   no warnings.  If it does, we have a bug.
