Add UI for explicit issue signoff

Active issue assignees will now have a button on issues to explicitly
'signoff' their assignment - that is, to affirmatively declare it done.
The use of this new action will allow assignees to signoff without
needing to close the issue as well.  This is useful for multiple
assigned users collaborating on an issue.

Note that if an assignee chooses to close a ticket directly, they are
still automatically signed-off, as before.

To aid this feature, the low-level definition of an 'assigned user' is
updated to exclude users occupying an assignment slot, but which have
already signed-off.

Since the icon representing this action is the same as for closing a
ticket, the buttons enabling these two actions are now color-coded
wherever they appear.
