Fixes for latest LiveScript

Don't know if you still using this module or not, but it wasn't working for me with LiveScript 1.3.1 so here's the patch.

If you don't mind, add me to github and on npm and I can publish and do some basic maintenance on this. It should really come with a compiled JS file IMHO.

Also, I reved major version since it seems that LiveScript changed a bit.
