[REVIEW-3-6] feature/masterpages

[Stefan Knorr]

Hello Björn, Petr,

can you please have a look at the stuff I've done in
feature/masterpages. To be quite honest, I haven't tried building with
it yet, so I don't know if Bright Blue works now from the template
dialogue or not. Otherwise, though I tried to do everything Petr asked
us to.

Also, I've removed a number of master pages, usually for size or license
reasons (Ron Faile hasn't given us a license statement, Mateus only gave
us one for a single template).

Regards,

Astron.
