Refactored XMLRPCManagers. Fixed bug that Managers would keep polling even when they were inactive. Added tabs with the description and torrents to the ChannelActivity.
Fixed bug where the polling wasn't handled, because the observers weren't subscribed

Started with making downloads work.

The downloadManager is now checking for updates. The Download class now contains an infohash parameter. A downloadAdcitivity has been added that does nothing yet.
Refactored code to no longer include th torrentmanager and torrent classes.
Added download and stream functionality:

-Made the downloads screen functional
-Updated the layout of  downloadListItem
-Turned the XMLRPCDownloadManager into a singleton
-Increased the polling interval to 2 seconds
-Added more fields to the download class
Merge branch 'master' into channelTorrentFragment
Updated ThumbItemtest and removed Torrent and Torrentmanager tests
Updated poller to be threadsafe and fixed and made sure no polling directly stops when pausing. Also tried to make a unit test for poller, but failed to get it running.
Updated XMLRPCManagers:

-Improved error messages in XMLRPCDownloadManager
-Made the pollers wait for the previous call to return
-Changed to polling interval to 500ms for torrents and channels. Kept it on 2000 for downloads.
-Connected to 127.0.0.1 instead of localhost, which should be faster
Made the layout for downloadActivity
Made the layout for downloadActivity
Changed the color of most of the layout elements to tribler-orange. The navigation drawer, search bar and scroll glow still need a color change.
