Present torrent files as a tree

A torrent info dictionary has two modes: single and multi files. When in
multi-mode, the name-entry is the directory containing the files.
Represent it as a tree.

During testing I discovered a fatal bug in the torrent parser: If we
encounter an invalid string, we have to move mPos forward, else we will
loop indefinitely until we're OOM.

I also added some icons for folders, files and trackers.
