I've ported halfnes to Browser

[neo-expert]

Hi, I have developed a JVM for browser and have ported halfnes to it, and it works! but very slow. look here:
https://github.com/neo-expert/halfnes

normaly my JVM-implementation is very fast. You can check it here:

Halfnes is an interesting project for porting. I'll check why halfnes is running slow on it. Normaly the browser should automatically optimize the code...
