Martin Gräßlin 4560f8d253 Handle ShellClient::windowShown in Workspace 
Summary:
When a ShellClient gets unmapped and mapped again the signal windowShown
gets emitted. We need to handle this in Workspace to ensure the window
is in the proper layer and gets focus.

This fixes applications like KRunner/Yakuake not having focus on a
second show. Unfortunately it also brings back the problem that
notifiations steal focus (this needs to be fixed by passing a proper
window type to a notification).
