Minimum version required is now 4.0 ... yes, I'm serious.
Hiding the "Open All in Tabs" menu entry should now work also for
non-english environments.
Added a space.
Made sure that only the PlacesToolbar is effected.
The height can now also be less than ~19 pixel.
Added an option to set the padding between the items.
Upped version to 1.1.
