EffectsHandler emits desktopChanged signal

Browse source 
The first signal used between EffectsHandler and Effects.
The signal is actually emitted by the EffectsHandlerImpl and only
the interested effects connect to this signal.
EffectsHandlerImpl itself is also notified by a signal from Workspace,
allowing to remove one of the many if (effects) checks.
