applets/kickoff: Add ability to run session management actions without confirmation

ivan tkachenko requested to merge work/ratijas/actions-skip-confirm into master

Requires patch in plasma-workspace/applets/kicker/ SystemEntry to accept and process the new argument.

Couldn't find a way to recolor buttons when all the buttons are held. Also can't hook into native QMenu wrapped in PlasmaComponents 2.0, so can't implement this for overflow buttons.
