[Phpwm] PHP Booking System

[Alistair Scott]

Thanks chaps

I've thought about this and I suppose I'm opening myself up to all sorts 
of problems if I have a complex booking system.

I think I might use a simple availability checker instead. I found this 
that looks like it might do the job...

There seem to be quite a few similar calendars around, so I'll have a 
rummage.
