Unify features and code used in the file listings in the files tab and the add torrent tialog

[ari-_-e]

In my humble opinion, I think that in order to ensure consistency, the code used by the two file listings should be unified. In the process, the features included in each one should be combined in order to form a single super-file-listing widget thing. In particular, the files tab can do sorting, and it can be used to set priorities other than just yes and no. The add torrent dialog can be used to set the priorities of all files in a directory, and can show the general status of its contents. I think these features should be merged.

I think the add torrent dialog is fine the way it is. It keeps it simple and I don't like the idea of adding a context menu to the file listing there. Some of the code could be unified though.

It would also be helpful to be able to rename file in the add torrent dialog.
