This patch adds 3 new configuration options applicable for subclasses of ALabel. The options can be used to execute user defined code in response to the 3 mouse events: * on-click: The left mouse button click * on-scroll-up * on-scroll-down This patch also modifies the behaviour of the format-alt toggle such that when the on-click event is configured, format-alt is toggled on any mouse click other than left click. When on-click is not defined, any mouse button would toggle format-alt. Signed-off-by: Harish Krupo <harishkrupo@gmail.com>
