Version 0.8.1

- Fixed issues with timer and updates
- Fixed issue where current mounted game was not updated in the
interface
- Favorites button on mainscreen is now disabled if there are no
favorites
- Handle disconnects and turn off xbox events (whoops, forgot those,
thanks MS, for not testing disconnects!)
- Removed support for cover in the XML (will use too much memory for all
covers if you have a decent amount of games installed)
- Download game information when viewing the game information, and not
when launching the application (less memory usage, but no support
anymore for cover and banner in the xml).
- Changed WrapPanel in Wall.xaml with VirtualizingStackpanel to optimize
performance and reduce memory
- Added support for hyperlinks (youtube trailers and info pages) in the
game information window
