Archive bin using keyboard shortcut

Fixes #756. Ref #1497, #1000.

Once archived I should be taken to my next bin. By next bin, I mean whatever appears next in the list of bins I see when I go to My Bins.

If this is implemented it will be easier to winnow my massive list of bins down to just those which I consider current/useful.

Hmm. Not sure I'd expect that or want that personally.

I get why you find it useful for grooming your current list of bins, but that one-off task aside, just like delete, once I archive, it doesn't mean I want to leave the bin, it just means I want to put it in the archive.

There's also the cognitive complexity of "what's the next bin?". Is it the next oldest? Next newest? What if there isn't a newer one? Do we go to the oldest? Does it do nothing? Does nothing seem like it's broken? When if I only have one bin?

Note: currently archive (as per the crappy homepage version) is only archiving snapshots, and not complete bins. This should be changed (but isn't easy - for the same reasons deleting the whole bin isn't easy).

From a technical perspective this is also pretty expensive to pull off: we need to run a fully query for all your bins, do relatively intensive sorting (which we already do, but isn't a reason to do more of it), and then serve up the next url - then handle what ever (convoluted?) logic that decides what's next.

Technical aside, I kind of feel like "archive + next" is a maintenance job that will only happen once in a while, whereas "archive this bin" I can see happening much more frequently.
