IE 10 Support

Hello there!

I've implemented a very basic IE support module that requires two lines in zepto.js to be changed. It works by adding the \__proto__ property to Object and referencing it to the objects prototype. I have only done quick testing of the code and found that everything works fine in currently supported browsers and I've only noticed a few animation problems in IE10.
I would like to point out that I'm only targeting IE10 since I am in full support of sticking to modern browsers and IE10 is a modern browser with a growing number of users so supporting IE10 with this small module that adds only a few lines of code would be a good move for Zepto. I would like to run a full suite of tests on IE but I'm currently working on projects that require my time and I only made this because of the reasons stated above.

I hope you like what you see and include the commits to the Zepto master branch.

UPDATE: updated the IE module to handle everything. No core file changes are required to make IE work.
detect.js and make file are changed to include IE detection and include the IE module by default to support IE10.

UPDATE2: here is a jsfiddle of the minified Zepto.js with IE support showing the snow example working in all modern browsers. http://jsfiddle.net/Jd3XS/   http://fiddle.jshell.net/Jd3XS/show/
