Working: most of the view, bulk edit toggle.

Enable bulk editing

The bulk edit sidebar is coupled to an issuable's DOM and expects
the correct information to be there in attributes or dataset.

Add pagination to Vue issuable list

Implement sorting and reordering in vue issuable list

Fix edge case in issuable ordering

In the Vue issuables list, the list now takes the sort key from
the sort dropdown. The server remembers the previous sort state
even if none is provided in the URL query string, so the
dropdown is the better source of truth.
