Title: Add button to toggle between copy and stage mode

in diff view. By default the diff view is in the stage mode (selected
lines are marked for staging) showing a button at the top of the diff
view to switch to the copy mode (selected lines can be copied into the
paste buffer).

Proposed solution for issue #161.
