Infobar UI cleanup on Mac. Adds the yellow background gradient and

centers all of the buttons.

Also adds the ok/cancel buttons to the xib file.  Infobars that do not
need the buttons can remove them from the view before displaying.

BUG=http://crbug.com/14462
BUG=http://crbug.com/17195
TEST=Infobars should have yellow background, look less ugly.
