Spoike 559144cb05 Updated font code for freecs's benefit.
added cl_iDrive cvar.
tried to solve invalid server address errors.
fixed envmap+screenshot_cubemap commands (they write slightly different cubemaps).
rework server favourites a little, to avoid conflicts with other engines.
fix legacy rtlights on certain maps.
added 'rgbgen entitylighting' for lighting with colormod support.
decompiler should cope with more instructions now. pretty much just switch opcodes that are bugged now.
implemented a couple of joint types into the bullet plugin. still useless though.
