--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
--Export For Backup, exports a layout with its entire
configuration for ALL applets
--Export As Template, exports a layout after the user
has chosen which applets should keep their settings
and personal data. By default Latte Tasks plasmoid
is going to propose to keep its data because no
personal data are kept in it
--onSomethingChanged syntax is preferred for all
slots that are triggered from somethingChanged signals
--doThis syntax is preferred for generic slots that
are triggered from various different codepaths
--add GenericDialog class in order to provide
same implementation for all settings::dialogs.
As a first step GenericDialog provides a common
showInlineMessage api
