Fix for Mantis 3064 from MageKing17: Adds more functionality to colors.tbl. * "#Start Colors" is now optional; no more need for a blank section at the start of a colors.tbl just to define some team colors. * "#Interface Colors" section added for redefining various colors used by the interface. * "#Color Tags" section added for redefining or adding your own text color tags. * "#Default Text Color" section for choosing what color tag is the baseline default for various different screens. * And the big one, support for *-clr.tbm modular table files.
