Switch from libglut to freeglut and retire libglut. Libglut hasn't been

developed in years and has been dropped from the MESA 8.0 distribution.
Freeglut is a rewrite of glut and is actively developed and is used by
many linux distributions instead of libglut.

Bump all ports that directly depend on libglut because of the shlib version
change.

There are some extra items in this patch.

*) Because freeglut doesn't have the same dependancies as libglut, some ports
	need extra dependencies added to USE_XORG to make them build.
*) Mark graphics/f90gl broken, f90gl depends on a header that is only shipped
	with libglut.
*) Remove option for libglut/freeglut selection in games/cake, only freeglut
	remains now.
*) While here fix a png related build issue games/vegastrike.
