Fix problem with "Cancel" text not double-bolding

This CL changes the way the "Cancel" string is bolded, so that it can automatically react to the "Use bold text" accessibility setting and double-bold itself appropriately. (Previously the bolding was hard coded in XML, this change allows TextView to handle its own bolding.)
