Bug 468531

SUMMARY
Two controls take focus when they don't need to:
1. The radio button for custom accent colours (also this doesn't highlight with focus)
2. The custom colour picker takes keyboard focus two times in a row

STEPS TO REPRODUCE
1. Click "From current wallpaper"
2. Press tab once
3. Press tab 11 more times
4. Press tab once more

OBSERVED RESULT
After (2): the radio button itself has focus (with no highlighting)
After (3): the custom colour picker has focus. There is a ring highlight around the picker button.
After (4): the custom colour picker has focus. The entire picker button is highlighted.

EXPECTED RESULT
After (2): the first custom colour has focus
After (3): the custom colour picker has focus
After (4): focus moves to the next logical control (should be the colour scheme picker but is actually the "Help" button)
