resource Booking features

• Each resource is given a separate calendar that is shared through the web site.
• Bookings can be attached to events in the web site calendar, so for example if a meeting is moved to a different time, the attached booking for a room/resource is also updated.
• Once a booking has been requested a resource manager is notified in order to confirm the booking.
• Double-booking is prevented as any potential clashes are recognized, reported to the booking manager and possible alternatives automatically suggested.
