Add option to change file name to make the home page look cleaner.

Adding the option to change file names would also provide a workaround for the bug that stems from the Android file system's alteration of filesnames containing a ":" (colon) character. (Currently, any folder or file with a colon in the name gets renamed by the system, causing tTorrent to fail to find the file & start downloading it again, which causes the system to rename that NEW file, which causes tTorrent to start downloading it again. Soon there is no space left & a long list of incomplete files numbered (1), (2), (3), etc. Choosing a new filename which does NOT contain : is the only workaround that I'm certain would work.) Currently it's impossible to use tTorrent to download a torrent wherein any file or folder contains a filename such as "Movie Title 2: Sequel Tagline". Being able to rename files prior to downloading would let users remove that pesky ":" & download the torrent as normal.

A destination file\folder rename feature would also make repairing (\"merging") torrents easier & more practical.
