ActFmDataService doesn't need to exist anymore
Killed more dead code
Don't record changeshappened for featured lists
Compute signature for sync api requests correctly
Fixed some bugs with creating signatures in ActFmInvoker
Fixed a bug when creating urls
Only enqueue changes happened messages if actual outstanding entries were recording. This could fix a bug where the queue would get filled up with pointless messages
Hopefully fixed a deadlock that could occur during database transactions (see http://stackoverflow.com/questions/11535222/recommended-design-pattern-for-writing-to-sqlite-database-in-android)
Removed references to deleted sync flag in test projects
