While here add a couple of patches obtain from the fedora project to fix
compilation with modern compilers and allows to build with lua 5.2
Switch lua to lua 5.2 version
Use desktop file provided by upstream instead of the version provided in
the ports (the upstream version is more complete)
Switch to USES=libtool
Now that overlinking is not happening anymore fix the glut version not
linking properly because it lacks an explicit link to libGL.
