fix #12,multi-screen support

--this commit is just a small clean up that
acts as a reference for all the previous
10-12 commits that provide the new anticipated
multi-screen support. With multi-screen support
the user can set for its docks either to be always
on the primary screen or an explicit one... The
docks are loaded and removed automatically on
screen changes
