elexis 415939b59b Introduce CGUIColor type inheriting Color type and switch the GUI to exclusively use that.
The type differs from the Color type, because contrary to Color, it can
be created from a color predefined in the GUI page (such as "yellow").
Move this predefined color check to the new class instead of hardcoding
it in FromJSVal / ToJSVal, GUIUtil, JSInterface_IGUIObject and to
straighten the latter.

Delete fov_wedge_color from Minimap, unused since introduction in
5275dc862b.

This was SVN commit r22558.
