Martin Gräßlin b19da3cb14 Move implementation of Client::packTo to AbstractClient
Method no longer virtual and only implemented in AbstractClient.
The implementaton works in a generic way nowadyas.

Added an autotest for the basic packTo behavior for packing against
a screen border. Packing towards other clients still needs adjustments
in the Placement code.
