Subject: [PATCH] Introduce new signal configChanged() to Workspace

To get rid of direct method calls and numerous #ifdefs a new signal
configChanged() is introduced to class Workspace. Every module
which is interested in reloading the configuration is needed to connect to
this signal.
Initially this is done for the reconfiguration of DesktopChangeOSD().
