Add window decoration to ShellClient

If a ShellClient supports the ServerSideDecoration interface we can
create a server decoration for it. For that updateDecoration is added
as a pure virtual method in AbstractClient and a more-or-less code copy
from Client is added to ShellClient.

Geometry handling is adjusted to consider the window decoration offsets.
