Add ability to populate "YEAR" tag in files in yyyy-mm-dd format, plus other tags

[Rings4]

Please allow the ability for the files to come with YEAR tag populated in yyyy-mm-dd format. On top of being one of the most important pieces of information to know for a song, this has the benefit of allowing us to listen to releases in chronological release order (or in reverse order).

As well, this would allow the ability of downloading releases into their own subfolders as it would 100% prevent duplicate folder names, especially when naming the subfolders as "YEAR - ALBUM". The vast majority of people who download music use one folder per release, so this would be a very welcome option!

Finally, please allow the possibility of saving the Monstercat catalogue number in a tag. The catalogue number looks like MCF036 and SILKM285.
