Improvement in the "Aero Snap" - with some functionality from Compiz Grid Plugin

Well, for now "Aero snap"-like feature is impelmented. I think it could be improved so it'd be much more kick-ass.

If you used the Grid Plugin in Compiz, you should know that you can use the Alt+NumPad# shortcuts to fit the focused window in the left/right/top/bottom/left-top/left-bottom, etc part of the screen. And if you press, for example, Alt+KP4, the focused window goes to the left half of the screen. If you press Alt+KP4 again, the window shrinks to 1/3 of the screen width and again sticks to the left edge. If you press the same hotkey again, the window is 1/4 screenwidth wide and next 3/4, 2/3 and 1/2. I used to like this feature and I think it would be great to see it in elementary.

But we can go further: Imagine that you drag a window to the left edge. Once you reach it, you see the stick-to-the-left animation. What would be great? To have the coolness that if you push the window harder to the left, to get "thinner" and "thinner" windows, sticked to the left. We could have this beautiness in the other direction too - for example, if you move the window a little bit out of the edge, to have larger sticked-to-the edge windows.

Aditionally, we could have corner/central hot spots for more flexible windows placement.

I sorry for my potato English. I hope you understand me though.
