Things are shaping up. A few more work and I'll reach the point of iso functionalities with the previous code. The GUI part is done, I just have to plug it with the existing engine.

I'm afraid I will not port the engine part to C++ for now, as it depends from too many things, themselves used everywhere in the app (Namedly SP desktop and the selection functions).

I also spent a few minutes to draw new icons for the align buttons. You can grab them from the sourcefore patch tracker. Here is the state of the beast

By the way, it remains only one required bug to fix for 0.39. This should come soon
