Rewrote much of the console code. Should be no obvious differences. Nearly all conchar parsing goes via a single function. Still some left in the dedicated server code. Added the ability to parse utf-8 text, disabled by default. Added the ability to input unicode chars using whatever keymap the user has set up in windows (not enabled by default). Reworked vbo stuff to be a little more versatile. Added toggle console command. Added freetype2 support (not compiled by default). git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@3234 fc73d0e0-1445-4013-8a0c-d673dee63da5
