introduce cocoapods integration

Hi,

I converted all of the stuff to CocoaPods to avoid git submodule dances and improve modularity.

I'm not implying for this branch to be merged due to some dirty hacks that still need to be applied (which should probably result in several fixes inside CocoaPods), however I hope you like the concept I'm trying to push.

The branch depends on CocoaPods and my local Pod repository which primarily contain your 3rd party libraries used within this project. Please see the `Makefile` in the root directory.

Running `make prepare all` should yield two buildable workspaces in `Debug Me` and `SuperDebug` directories.

Eager to see your comments.

Cheers,
Vladimir
