Title: Pinch to zoom

I little something I find useful I want to share.
Very handy when using the Apple Magic Trackpad.

Those commit allows one to smooth zoom using the pinch gesture.

I modified the zoomable class to handle pinch gesture.
Then modified tilesetview and mapview to delegate their pinch gesture to zoomable.

I used Desktop Qt 4.8.1 for GCC to develop.
And I only tested this on Mac OS X 10.8.2.

PS: I am not a big fan of C++ nor Qt, but I must admit that this project is one (if not THE one) most well coded C++ project I have seen in a while! No wonder why the product is so robust and fast, apart from being extremely useful too :)
