Allow removing active group. 

This is an artificial restriction that serves no useful purpose.
Just switch to the previous group if asked to delete the current
one.

The ClearSuper() calls are reshuffled, since TW.ClearSuper() calls
TW.Show() and so has to be called while the sketch is still valid,
whereas GW.ClearSuper() also recreates the default group and thus
it should be called after the first RemoveById+GenerateAll pair,
or it'll recreate the default group before the entities on it have
a chance to be pruned.
