Use strings as properties to allow property mangling.

[jespertheend]

Right now when minifying scripts, things such as gltf parsing break because the properties have been mangled.
We should use x["foo"] and { "foo": true } syntax to make sure these props don't get mangled.

On top of that we should add a way to write tests that run on minified builds.

So far these are all the strings I was able to find that break because of this:
