Add the new bookings system

[ilgazer]

I added the new bookings system as an iframe, and reverted all of the booking-related links to their old state.

Very nice new system!

Two things I quickly found:

• Visually, this white triangle isn't fantastic. Maybe we can make this also the same purple?
  
• Am I correct that the booking system is only in English? On the Dutch page, the iFrame is still in English

What do you mean by the white triangle? Also, I forgot to add dutch support but can do it without much difficulty. Also, do we want a way to put separate english and dutch title and descriptions?
