** BIG COMMIT **

- Fixed a bug in options (scan dir widget were not initialized well, still disabled when they shouldn't)
- Fixed a bug in scan dir (doesn't display torrent addition dialog several times for the same torrent if we don't close the dialog before next scan refresh
- Splitted GUI from Bittorrent, lot of code rewritten and optimized. Code changed so much that we will spend the next few days squashing eventual new bugs ;)
- We don't use the hash table to store the torrent handles anymore because libtorrent is already doing it for us (save memory)
