Added scripts needed for reservation creation and modified database creation script
-createUser.php runs first to create a new entry in user table
-createCustomer.php runs next to create a new entry in customer table referencing the created user
-createReservation.php runs to create a new generic reservation referencing the customer created
-createRoomReservation.php runs to create a new entry in roomreservation referencing the generic reservation that it belongs to
-Modified dbscript.sql to to add in a roomReservationID column as the primary key instead of the reservationID foreign key
