I removed all the risky innerHTML / outerHTML bits

And more important removed the (MF) out of the catalogue number display so that I can double+click copy catalogue numbers easily and fast as before

I added use strict for safer run and debug.
Replace getElementsByAttribute by standard querySelectorAll.
etc.

2012.1102.1228 now works even when not coming from MB (will prompt for MB release on click)

interactive mode + better HTTPS:///MB manage (as I don’t like adding stuff in URL, it prevents clean URL copy/paste)

of course another FFF bug (document.referrer)

2013.0511.2324. minc.gr.jp changed their URL patterns (to MS asp yuck)

Can you support multi-disk release?
For example:
http://musicbrainz.org/release/60f5cc7c-a2bf-43cd-a751-33253b19abc2 and
https://www.minc.gr.jp/db/AlbInfo.aspx?SHIYOSYACD=0000024&CATALOGCD=KICX-006202&SETFLG=1 (KICX-6202)

If there is no technical difficulty and you just don't have time to implement, I would implement it and send PR.
