Link to iAd framework
iAds are "in"

The feature doesn't really work, but I'm done with spiking. I also
cleaned up the layer a bit, removing the superfluous Navigation
controller.
WIP: Start showing ads

This is a big change. For the first time I've got some cocos in the game
logic, in the form of a CocosDirectorAdapter.

You can create an AdDelegate with a director interface. In order to get
the interface to work with CCDirectorIOS we wrap it in an adapter. In
order to get that under test I've redefined CCDirector.m in the tests,
thereby allowing it to be instantiated via a link seam.
Pause and resume on add actions
Get the Link Seam working with tests

I know have the cocos director adapter under test and the link seam
working. I'm working towards add serving as a seperate use case of the
system.
