Switches should be keyboard navigable

[ryanflorence]

tabIndex="0" should do the trick.

Also, keyUp of "Space" and keyDown of "Enter" should activate them.

For radio groups, only the active radio button should receive focus on tab, subsequent tabs should jump over the rest. Once one is focused, arrow keys change the selection.

Also, lots of aria stuff for these:
