Update for the test version (alpha) 4.4.13

► Facebook. Fixed authorization. TThe service is still unstable, due to changes in the API. ► Twitch. Added auto-selection of the server, in case the current one stops working. Removed the message about the disconnection (I'm not sure if this is a good idea). Fixed a bug that could cause the program to crash if the server is unavailable. ► DLC. A new addition is attached. If all tests pass, then within the next 1-2 days there will be a release.
