Taskbar+WindowServer: Adding to Quick Launch via windows :^)

Browse source 
You can now add applications to Quick Launch via the context
menu option of their windows. Clicking it creates an event with the
stored PID of the process that created the window. The Taskbar receives
the event and tells the QuickLaunchWidget to add the PID, which then
gets the executable using /sys/kernel/processes. It also looks for an
AppFile using the name from the process object and if there is one, it
uses that, since it should contain a better formatted name.
