- hooked up the colorization feature.

It can now be used from UDMF and ZScript.
To avoid clutter it doesn't allow setting the values individually but requires definition of a data record in TEXTURES.

colorization
{
    DesaturationFactor <float>
    Invert
    AddColor <color>
    ModulateColor <color>
    BlendColor <color>, <mode> [, <alpha>]
}

Mode for BlendColor can be Alpha (normal translucent blending), as well as 3 special values taken from Build engine games: Screen, Overlay and HardLight.
