Option to raise bouncing appicons

If the appicon is not in the dock/clip, or the dock/clip is not set to
"Keep on Top", there's a good chance you won't actually see the bouncing
because some other window is covering the appicon.

Besides adding the option to raise bouncing windows, this patch adds a
utility method to move a window back into its correct stacking position
after it has been messed with using XRaiseWindow.
