Pending JPetStore Checkin

[Scott Semyan]

I have a pending checkin to the JPetStore sample. This check-in
incorporates using Derby as the data store and adds new or improved
functionality such as multiple addresses, add/edit new user, admin of
the DB, etc. I also fixed many bugs. 
 
This checkin is currently being code reviewed and should appear in the
trunk shortly.
