Initial feedback module

- Code uses block and requires 10.7, despite of the deployment target being set to 10.5
- UI hasn't been tested with 10.5 either

Lots more fixes to make it actually build

Add block based NSURLConnection category

This allows to use block based NSURLConnection calls that are not available in 10.6. (Apples implementation is also buggy in 10.7)

The code is based on Plausible Labs `NSURLConnection+PLFoundation.m` and slight adjusted
