since we want to make some tabpanels lazyitems,
we have to change the behaviour of the configpanel
and the subconfigpanel
in the configpanel, we have to manually fire the hide event
for the tabs which are lazyitems, because they will not
be direct children of our tabpanel and thus their
hide event will not fire
in the subconfigpanel we have to manually save the to
be active tab, since at this point, the subtabs are not there
yet (and cannot be activated)
also in the afterrender event, we only want to set the
activetab when we have none, and we only set the first,
if we have none saved

This takes a bit of screensize, but is fine as long as the browser
horizontal screen size is at least 1280 px ( 92 % of desktop users in 2016
according to StatsCounter)
Still usable for the remaining small displays, but horizontal scrolling
is needed for grids with a lot of columns.
Moving the sub tabs to the top left provides a minor usability
improvement as all controls are now grouped together in the same
screen region.
