--Move in a simpler layouts approach.
--Single Layout mode loads ONLY ONE Layout for ALL Activities
--Multiple Layouts mode loads any combination of Layouts based
on the following settings:
-- OnAllActivities
-- ForFreeActivities
-- SpecificActivities
--when hidden configuration windows are deleted memory
consumption is improved and provides much lower values
--when hidden configuration windows are not deleted
memory consumption increases but their responsiveness
for hiding/showing is instantly
--add GenericDialog class in order to provide
same implementation for all settings::dialogs.
As a first step GenericDialog provides a common
showInlineMessage api
