WIP: Handle faults returned from rtorrent

[wheelerlaw]

Description

When rtorrent encounters an error interacting with the xmlrpc interface, it will return a response with a <fault>...</fault> tag in the response body. Currently Flood doesn't handle this tag in the rtorrentDeserializer.

Related Issue

#840

Motivation and Context

Flood doesn't display the original error returned back from rtorrent, and any useful context that the original error message may provide is lost.

How Has This Been Tested?

Haven't tested it yet, just proposing changes.

So with the changes, the original error message makes it back to the client, but I still need to build in some functionality into the add files modal to handle errors from the server.
