Restore button and make it work with new merge buttons.

I was missing the feature that selected all checkboxes when none was selected upon clicking the merge button so I fixed that part which also restored the "clear queue" button. Though I didn't test the latter.

Thank you, I've been missing this, too!

I moved the unrelated feature to #933.

I’ll have to at least make the react-hydrate new hint: custom mb-hydration event infinite loop workaround…
