I modified String.prototype.trim to a smaller version, which is attributed to MDN.

Before my revision we were at:

Minified: 24.916k
Minified and gzipped: 9.080k, compression factor 5.599

Now, we're at:

Minified: 24.897k
Minified and gzipped: 9.080k, compression factor 5.608

I'm not sure how to remove commit 4c557d1, but it's already been merged.

Commit to reduce the size of Zepto.
Now using the official MDN String.prototype.trim polyfill, as
opposed to our own home-baked one.

The Uglifyjs compiler doesn't make this optimization, but Google's
Closure uses inferred types to make "safe" changes like this:

if (x === undefined) {
    x = foo();
}

to:

x = x || foo();

UglifyJS doesn't make these changes. We might want to consider
moving to Closure compiler, if our aim is to produce the smallest js
possible.
