Title: General JavaScript optimization for better minification and performance.

Replaced "==" for "===". Zepto SHALL NOT sacrifice performance quality for size.

"window" is now a "internal var" for optimum performance and minification.

isF now uses "typeof ==='function'". Looks like someone got confused by jQuery generic "type()" function (just look at jQuery's isFunction).

"void 0" replaced and killed "undefined". Is faster, smaller and ninja.

Removed some "===false"... smaller and faster.

Minor fixes.
