Automatically Find Alternatives

The point of this program is to make it easier to manage duplicate files. If the program picks a bad file to preserve, the user should be able to point it to the file and say "give me some alternatives". The program will then query its database and copy some alternatives from the duplicates directory to the current one.

This creates an additional problem of what to do with the original file, since it was never copied to the duplicates dir. Perhaps the thing to do is create a "swap" command to put the current file into the duplicates dir and replace it with a file from the duplicates dir.
