--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
--curent view indicator config ui is not deleted
when the PrimaryConfigView changes its parent view.
For each view there is one indicator config ui
that is kept available to be shown when appropriate.
This way we avoid unnecessary recreations of indicator
config uis when the user cycles between different views
settings.
--when default indicators are reinstalled then
views do not have to be reload its sources. The user
is expected in such cases to restart Latte. At the
same time installing Latte multiple times does not
create too many views recreations with no real
reason
--enabledForApplets and lengthPadding for indicators
has now moved to indicators responsibility to handle
--as a consequence usesPlasmaStyle has been removed
from indicators API. The corner cases that indicators
conflict with plasma theme applets should be handled
differently and in a different way
