Fonts: Colors and dimensions

[OnlineCop]

We should have a class/struct for fonts and either blend or remove one/both of the eFont/eFontColor enums. If we have a std::map or std::vector of fonts, the enum values could still be used to indicate which font we're after.

enum eFont
{
    FONT_WHITE = 0,
    FONT_RED = 1,
    FONT_YELLOW = 2,
    FONT_GREEN = 3,
    FONT_PURPLE = 4,
    FONT_DECIDE = 5,

    NUM_FONTS // always last
};
enum eFontColor
{
    FNORMAL = 0,
    FRED = 1,
    FYELLOW = 2,
    FGREEN = 3,
    FDARK = 4,
    FGOLD = 5,
    FBIG = 6,

    NUM_FONT_COLORS // always last
};

The struct should include the font dimensions (height, width) since these are monospaced fonts, and possibly color (or at least an index value within pal[] if we're wanting to recolor them).

KDraw::print_font() typically multiplies the font width by some offset, and I'd like to replace those Magic Number multiplications (* 8 ) with * font.width() or something similar.

This should also make it easier to extend the fonts in the future, in support of localization in case the current fonts.png doesn't contain all the necessary characters.
