New icon + ability to pause

Gave the app a new icon (not made in MS Paint this time) and the ability
to pause gesture tracking if you left click on the icon.
Added volume speed increase setting

Added ability to speed up the volume changing speed from within the
settings file. Also made it so settings stores the current application
version, making sure we're using the latest model for the settings data
(and wiping the old one out, at least through the alpha stages)
Fixed pausing function

Pausing was firing on both left and right mouse clicks. Updated so it
only fires on left click actions. Also updated the mouseover text so it
will show as paused when looking at the application name.
