[STUMP] [Patch]: a new hooks

[Michael Raskin]

                Hello
        Attached patch adds a new hook that allows to track frame 
splits with some context. Rationale: I try to keep some metadata about
frames (just tags, actually), and I want both children to inherit
parent's tags on split. That way I can have frame groups based on 
tagging, use window tags instead of groups and have some convenient
sets of frames to be replaced on "window group" change, not just entire
screens (as is default now) or heads (as it could be with some 
proposals). Patch seems nonintrusive enough..
