Fixed up display to set new display modes and fullscreen does not
properly work but it makes the window as large as possible (picks the
first DisplayMode from getDisplayModes() ).

Made the colors in TextWriter static so they don't have to be held in
memory for every instance of TextWriter and is easier to access. From
now on, access them as TextWriter.COLOR_NAME_HERE instead of
textWriter.COLOR_NAME_HERE.
