Make finish document use a checkmark instead of a lock

[jcklie]

Is your feature request related to a problem? Please describe. Finishing a document for a user is about finishing, not locking, so the icon is maybe unclear.

Describe the solution you'd like Use a checkmark instead and change the tooltip

So the icon serves a double-purpose. It shows the current state and it toggles the state. So if the icon for finishing is a checkmark, what should the icon turn into when the document has finished?

That said, the icon for finishing a document in the dynamic workload mode is a checkmark because in that mode, there is no double-function. Clicking on the button finishes the document and takes you to the next and there is no way to go back.
