Add .tags command

.t(ags) takes an ID, returns title, faves, plays, tags
strongly borrowed code from .info
Recolor .tags response
Added better colouring and added missing quote in handler setup.
New IRC command '.t(ags) <id>' to receive more metadata on a song.

This works similar to '.info' but instead returns artist, title,
album and search tags. And is accessable by non-operators.
