Now with propert suite/test separation (ocunit treats each class as a suite). Could use some prettier formatting and symbolic stack traces, but it's good enough for now.

Improved escaping of strings.

Wow, this looks awesome - I'll definitively give it a try! Is this a standalone class that just needs to be dropped into the project?
Edit: just found out how to set the observer in the plist.
