Plank overlaps with windows that reserved workarea space

[swissiety]

Plank overlaps with panels although the panel is reserving screen space via workarea. This happens e.g. when the xfce4-panel is on upper side while plank is on the left side with the fill alignment option selected. As a result both overlapping windows are changing its stacking order which is quite annoying. The modification should fix that.

Note: make sure plank is executed after the panel reserved its workarea space to see a different behavior.

As workaround for this issue I insert a space via a special .desktop file that has a transparent icon and opens plank preferences on click. ;-) Hope this gets merged as soon as possible.

this patch is pretty important to use plank sideways and is sad that more than a year latter nobody answer whats wrong or merge this PR.
