Title: Optimizations

zepto.js
- using === is faster than == . Devices are slow and 1 operator is just too small.
- better "isF". jQuery uses a generic function with toString, necessary for Array (cause of Opera), not necessary for zepto.

polyfill.js
- replaced "type.prototype.function===undefined" by "!type.prototype.function". Smaller and faster;
- smaller trim regex (inspired by jQuery);
- faster and still "ECMA compilant" Array reduce function. Faster and smaller;

I hope you all like it.
