* A seperate variable for hashing state, now properly restarts hashing

after restart.

* Stop a torrent and show a message when it finishes the final
hash-check and finds some chunks incomplete. This prevents full disk
from causing a torrent to go into an infinit loop of re-downloading
the data.

* Moved various slots from core::Manager to core::DownloadList.
