Reimplemented the _FREEFONT command

Browse source 
A new function has been added to parts/video/fonts/ttf/src.c, FontFree().
This takes an index into the fonts array, and calls FT_Done_Face() on the
handle, free() on the ttf_data then sets in_use to 0.

The sub__freefont() function calls FontFree(), and sets the appropriate font[]
element to NULL (after checking the passed font handle is valid, of course.
