Realized what an idiot I was for not using MPD's database,

so removed external tool tagging/tag reading requirements. Makes things
a LOT smoother, especially since ffmpeg and exiftool was where most people had issues.

Added "radio station no repeat" (don't play the same song AGAIN for X

time), fixed bug with weight matching, fixed error if there were
multiple copies of the same instruction.

Of course I forgot the docs

Added weighting properly back in

* Fixed bug where tracks > 60m would pass through length filter

* Redundancy add - if "artist" tag is empty, "album artist" tag will be used instead for artist frequency. Likewise, if "album" tag is empty, the "title" tag will be used instead.

Because of course you notice it after you tag it.

Significant rewrite, making it a single-run process instead of loop

working, tweaking what happens if it can't find a match
