Classes are not supported

This one's really simple.

new Sandbox().compile("class Test {}");

leads to

ParseError: Unexpected token after prop: T: class Test {}

I understand the readme says ECMAScript support is only "90% completed", but with such a basic feature as classes missing, about 99% of modern JS programs simply won't compile. That makes this library effectively useless, and should be fixed ASAP.
