#18 Metadata

[Rei]

This is a suggestion to piggyback metadata over the MUTE protocol. Metadata is such an important,
useful thing because filenames are so inconsistent/unreliable and give so little information.

Piggybacking ideas could be implemented through things like:

- Unusued protocol options
- Extended info on the filename that gets parsed out before display
- Additional metadata files that get searched for as well.

Metadata is painless to get these days, with tools like libextractor out there.

Oh, this would be ever so nice a feature, ever so nice...
