[openbox] Multihead window placement in groups

[Aphyr]

I wanted to mention that I recently removed the smart multihead client 
group placement code in place.c from my local copy of Openbox. If you 
aren't familiar, it will always place windows on the display of the 
first other client in the group--even if that display is full or the 
pointer is active on another display!

This means it's actually possible to place new browser or terminal 
windows on whichever display is active, instead of being permanently 
locked to one. It seems much more usable now. Perhaps there should be an 
option to configure this behavior, or at least disable it for certain 
client groups?
