Added:
	index.jsp - Simple landing page to choose between updating existing
registration or starting a new registration.
	update.jsp - Same layout as registration.jsp except it prepopulates
fields with existing registration data.  Still need to work on code for
selecting menu options where data exists.  Currently looks like new
registration menu defaults.
	
Changes:
	RegistrationController updated to support existing registration data
retrieval.  
	
Bugs:
	update.jsp
		- All menus display default options like in a new registration
		
	RegistrationController 
		- Unable to successfully retrieve emergency contacts for an existing
player registration.  Registration and Player data come back fine,
getEmergencyContacts returns an empty list.
		- Need to add code to decompose birth date and phone numbers into 3
separate strings to send up to the update.jsp for display
