[MetaDisplay] Added window-demands-attention signal

Browse Source 
Having a MetaDisplay::window-demands-attention signal allows to deal with
windows demanding attention in a cetralized fashion.

The signal is emitted when a window is created with initial demands-attention
state and/or when the state changes later on.

Based on original patch by Jon Nettleton.
