--fix case that indicators config uis were lost totally
during recreating a view that was using a custom indicator
and that custom indicator was updated.
--fix case that custom indicators were not assigned any
more to their original views when the dock settings
window was created first time for them.
--the new approach is much more memory efficient
as the same indicator config ui is used for ALL
views and anything related to config uis is now
handled by the manager instead of each diffent
view on its own
