Code Issues Activity Actions

FileManager: Move delete and force-delete actions to DirectoryView

Browse source 
This is a little bit messy since the left-side treeview also has a
delete action. Because of that, we have to put a focus-dependent action
that delegates to the relevant view-specific action in the tool bar
and menu bar.

I'm not sure yet what a good abstraction would be for this. We'll see
what we can think of.
