* Try to get the project file close to what we originally forked from Spotify.
* Remove the unit test code from the CocoaLibSpotify target.
* Restore the run script that downloads libspotify but add a "kill switch" that aborts it. If the COCOALIBSPOTIFY_SKIP_DOWNLOAD environment variable is set, libspotify will not be downloaded.
* Remove the Outreach, AppStore, Dogfood and AdHoc configurations.
