BUG dual color buttons don't work

[darkmas]

Color buttons defined in the fixture editor as having two colors don't show up as a "split" button with both colors in sunlite. Instead, they simply show up as a gray button with the first few characters of the color name". To test this - use any fixture definition that includes dual color buttons and look and the resultant generated page in sunlite. They show up fine in the fixture editor.
