Add Recode button to track editor

[AsstZD]

It would be nice to add a re-coding button to each field in Track properties editor. It should ask the user for encoding name, and translate the corresponding field as if it was in given encoding: (UTF-8) ä -> (Latin-1) #228 -> (User CP, f.ex. cp1251) #228 -> (UTF-8) д

it would indeed be nice to give users a way to make their tags actually match the standard they're supposed to be in, as per the format of tag used. There's a lot of minor things like this that would be of benefit in a tagger and not a lot of room for controls though, so we should probably give some thought as to ui before doing things like this.

As far as I know, mutagen will convert to Unicode if you just save the
file? Not sure we should go beyond that.

[reacocard (reacocard)]

Mutagen will handle encodings correctly if and only if the file was encoded in the standard encoding for that tag format. If it was not (as a fair number of older id3 files from non-latin locales are), then having a way to convert from a legacy encoding to the proper one would be useful.
