[compiz] Placement plugin enhancement

[Bellegarde Cedric]

http://puffy.homelinux.org/~gnumdk/compiz/patch/place.patch

Here a new version of my patch.

It now have six placement mode (kwin placement modes):
- Cascade
- Centered
- Random
- LeftCorner
- Maximize
- Smart

Currently, smart placement isn't present in this patch.
I'm working on it but my ubuntu(feisty) have really strange behaviours ... I 
can't debug compiz anymore.

I will work on smart placement at home on my debian...
