Subscribe for mouse scroll events on the pulseaudio widget
and change volume when event is received.
Scroll up increments the volume and scroll down decrements it.
These events are only subscibed when there are no user defined
commands present for them.

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.
