Merge development into master

For the two builds that I use regularly, the development branch is more stable than master at the moment:

* __iOS:__ The Xcode project is broken on master, on development it is fixed.
* __OS X:__ The OS X host from master crashes when running our game (and the flower samples, #723), the one from development works fine.

What about the other builds, i.e. __Windows__, __Linux__ and __Android__? Do we also care about Chrome, Blackberry and FlasCC right now?

If all hosts are in equal or better shape on development than on master, I think we should merge (given Patrick's approval).
