Review request for Plasma.
Summary
-------
Currently new containments are placed on the desktop based on the screen affinity (e.g. "belongs to \
screen 1"). This obviously doesn't work well when we have overlapping screens according to x.org (lies! \
damn lies! ;) and it makes dealing with on-the-fly changes to screens a bit annoying. It also raises \
problems for adding new desktop-y containments which aren't associated with any screen.
This patch implements a (trivial, even mildly naive) system of laying out the containments in something \
of a grid-like pattern, slotting containments when they change in the first available space.
I considered going for a strictly grid layout based system (and even just using a grid layout itself) \
*but* the following considerations prevented me from going this route:
* I do want users to eventually be able to click and drag containments into (to Corona) random groupings \
(spacial properties)
* We are likely to have non-Containment items on the Corona at some point, Panels already have their own \
layouting system now, and so using a stock layout or any other such layout mechanism would be full of \
special cases anyways

Testing
-------
Using it with two desktop containments, which are set to overlap on startup in plasma-appletsrc. The \
repositioning successfully moves them apart.
Thanks,
Aaron
