Allows overwriting entry path based on it's extension / mime-type.
These work only if python is aware of related mime-types.
path_by_ext:
torrent: ~/watch/torrent/
nzb: ~/watch/nzb/
This works always when server sends correct mime-type. A bit harder to use tough.
path_by_ext:
"application/x-bittorrent": ~/watch/torrent/
"application/x-nzb": ~/watch/nzb/
