Reorder mediums when sorting releases

[jesus2099]

In release merge page, reorder mediums (bottom table’s groups of tbody > tr) when sorting releases (top table) by MBID age.

Build a reference to each medium — and pass it to sortBy(what, mediums) ?

Each medium starts with a tbody > tr.subh > th > input[id$='.release_id'][type='hidden'] (.parentNode.parentNode) and ends with the tbody > tr:not(.subh) that is preceding the next tbody > tr.subh or that is the last row.

I already did the medium/release matching in #114.

I am not sure exactly in what order it is initially proposed, though. Something like that, maybe:

• release 1 (3CD)
• release 2 (2CD)
• release 3 (1CD)

Then

• medium 1.1
• medium 2.1
• medium 3.1
• medium 1.2
• medium 2.2
• medium 1.3

So, if it is correct, when we reorder as:

• release 3
• release 2
• release 1

It should then become:

• medium 3.1
• medium 2.1
• medium 1.1
• medium 2.2
• medium 1.2
• medium 1.3
