First crack at the edit child dialog that allows us to edit the
individual workout.  Right now we have passed all the data, in that
movement, into the integers and strings required and given them to the
fragment.  Still need to build the .xml for this edit, and put in the
proper logic for hiding/zeroing certain items to ensure data integrity.  

Also put in a timed_type sting so we don't double use the named workout
string, as its possible to have an amrap workout that is also a
hero/named workout.
