Add browserify support

Could be fun to have people running servers and clients in the browser, players could ultimately connect with WebRTC.

if we do this, i think it should just be a vanilla based server, very limited in its capabilities. The host may not have a beefy enough machine to run a client and the server at the same time if too many people connect.

The notchian minecraft client already runs a local server.

right, but thats on the pc, and most people don't "share" that one, they use real servers. WebRTC is going to tax the system much more heavily than a pre-built java runtime. At least thats just my opinion.
