New Bitmap draw mode for Freetype2 fonts.

The library can load any font supported by the Freetype2 library or
used the internal bitmap font.

With both types it's possible draw the text as texture or bitmap,
and using texture it's possible rotate, scale and clipping text.

Still have things to fix/add, but I think it's ready to move-on
and start droping the old api, most of (if it's not all) the
editors/interface/text.c will be remove, but some things still
has to be define, like:

 * Where is store the fonts ? (default font, panel font, filesel font, etc)
   I mean, every space have own fonts ? or we keep it on the context ?
   It's not a really problem from the blenfont side, because every font
   have reference number, so it's load only the first time.

 * What we do about gettext ?
   Keep the old system that call gettext inside the blenfont or replace
   it for _() in the Blender source ?
   Also things like pupmen has to be take care, if we want translate the menu.

Ok, time to sleep, back tomorrow to start moving the things :)
