different colors for different tiled images in debug mode.

Browse Source 
If there are multiple tiled images as overlay, it might be important to
see how they are loaded. Different colors in the debug mode for the
different tiledImages visualize that. DebugGridColors have to be given
as a sting array with a color for each tiledImage. However, shorter
arrays will be recycled without error. Also, single strings are treated
as single entry arrays, for backwards compatibility.
