uTorrent 3.3 BETA Build 28893 torrent

This is a beta (expect bugs!) of µTorrent 3.3, where we've rewritten some pretty major, problematic sections of code. The biggest of these rewrites was disk i/o, to improve overall performance at both low and high speeds, whether writing to local disk, a RAID or a network drive.

Please try it out and report any issues. As I mentioned before, this is an alpha, so there could be hangs, crashes or other problems.
Release highlights:

Disk I/O system completely rewritten. Now multi-threaded and high performance. It will take advantage of multiple disks, perform better with even just one, and no one disk job can block everything (e.g slow network blocking local I/O, or allocating files)

Auto-labeling and per-label download directories (Preferences -> Label)

Search items in Advanced preferences

Paired device removal
