Turned layout()->activate() into a new virtual function, 'activateLayout()',

which is called at the same places.

Mosfet: This is necessary because we are converting to not use QLayout
in clients. Without this, you can't get the right size for your windows.
Just implement it in your client and do your layout in it (surprise, eh ?)
