Tiling keyboard shortcuts (a la Winsplit Revolution)

[steve9000]

Hi all, the old style maximize-{horizontally,vertically} shortcuts aren't good
enough any more on our big screens. There's a really sweet program for
windows "Winsplit Revolution" (http://www.winsplit-revolution.com/) which
does a really good job. I'd love to see this as a core part of compiz.

I have attached a really simple implementation which does the simple stuff.

Stephen.
