Subject: window: Add configurable mouse actions for titlebar

Adds support for configurable mouse actions on window titlebars,
including middle-click and scroll wheel events.

New actions added:
- close: Close the window
- raise: Raise window to top
- toggle_stick: Toggle sticky state (all workspaces)
- toggle_above: Toggle always-on-top state

Fixes #425
Fixes #787

Note: requries matching mate-control-center changes to work properly
