added con_drawHelp and con_col*
letting the mod know we support the "cap_ExtraColorCodes" extension
con_colText overrides ^7 in the console and the help panel
extended console back scroll arrows all the way
only apply hw gamma ramps where and when needed
fixed the start-up console window staying visible when starting in full-screen
black window background to avoid the white flashes when hw gamma is enabled
use the "premake" tool from the cnq3tools repo with
"--quake3dir=<q3dir>" to generate a VS sln and gcc makefiles
this changeset also removes the "clever" handling of fullscreen/windowed
changes which didn't actually work and just broke windowed mode
