* Replace DejaVu with Biolinium for the existign sans-styles.
* Add additional sans-styles using Biolinum.
* Update the GUI style definitions to use the sans-styles instead of
serif styles.
(Wait with updating custom defined fonts in strings, as it will cause a
mess with the internationalisation that's about to be included)
* Add fonts from the quite complete FreeFont family as fallback fonts.
* Render all glyphs supported by the different fonts to support as many
scripts as possible.
* Fixes#2457.
(Now hope I included all needed files)
This was SVN commit r14853.
Rewrite font builder tool to be much simpler and to support more text
effects.
Change GUI to use new set of fonts.
Switch font textures from TGA to PNG so they're easier for the font

Greatly improve text rendering performance by using vertex arrays.
Fix rendering code leaving vertex buffers bound.
Add 'clip' property to GUI text objects, to disable clipping when
