Twabbit updates now support main tile update, not specific account updates.

I downloaded Twabbit when it was made free for a limited time a while back. It is a fun Twitter client to use. 

Change logs:

1. Auto streaming option while application starts. After streaming First tweet always provide option for loading more tweets that by design
2. Background tasks update main tile now and not account specific tile. Also removed account specific tiles
3. Bug fixing
