window layouter: label-dependent window policies

Browse Source 
This patch enhances the layouter to apply a label-dependent policy
for the placement of new windows. The policy may contain the
attributes 'xpos', 'ypos', and 'maximized'. If the latter is set
to "yes", the matching window will appear in maximized state.
