JavaScript CreateFixture method no longer accesses global world variable...

This fixes the problem from #49 and adds a GetWorld method to b2Body.

The compiled JavaScript files need to be updated by someone else, because my version of emcc creates a ~30kB larger output file and an additional .mem file.

Somebody give this guy a medal, and get this merged into the repo please!

You can get the version I compiled here https://gist.githubusercontent.com/zilluss/ccdf2c17c2d8577ea4dc/raw/14deed4733a4e3798c0993b07e0d76c8671f59ff/liquidfun.js

But as I said, it's a bit larger. The new emcc also fixes #50 partially, so the lengths of positionBuffer/particleCount match, so you don't get problems when rendering them as GL_POINTS. But CreateParticle still creates some strange particles that behave like b2_staticBodies :(

So, is there any chance of this getting merged?

Thanks, though this now needs to be rebased.
