changes
Login.jsp - formatted code and moved around html elements.

security flaw

there and not in get
	- This checking of username/password was moved to Users.java as per the
specification
	- Removed unused code and unused imports
	- Only 1 error message. States "Incorrect username/password" by giving
whether it is a username or password, that is a major security flaw

Users.java

Forms can't be imbedded in other forms. Seperated the forms.
TODO: With pulling the BookingHistory form out of the FlightSearchQuery

be needed to get the button to line up with the other button.
