Stripping garbage from track names

Some internet services provide tracks with many garbage in the tags. This garbage seems to be at most common between services(for instance youtube and soundcloud connectors share (mostly) same function for stripping that garbage). I think it’d be better to implement one global anti-garbage function and put it to the core.

Further discussion topics

1. Can such function be incompatible to some services?
2. If artist and title are in the same string(what a pain), is it better to remove such garbage before or after separating artist from title?
3. Should we provide ability to add more garabge-detecting regexes for users?
4. UPD Sometimes connector should be able to pass more than one variant of parsed {artist, track}(when artistTrack is ambigous, e.g. "artist with- dashes -track title" or some cases like username on soundcloud). last.fm should handle such cases better than we can do.

@inverse I think we should get rid of v1 connectors first.

Should we provide ability to add more garabge-detecting regexes for users?

It’s supported already:

1. Connector developers can add new rules (regexes) to Metadata.YoutubeTrackFilters object to update MetadataFilter.youtube behaviour.
2. They also can write custom filter functions with usage of regexes.
