Building is now done by install package's script.

Hi Alex,

A little pull-request just to get lib/ out of versioning. npm install is now responsible for this, as described in http://npmjs.org/doc/scripts.html

In my opinion, it makes sense since src/* are the only files we really want to be under version control, but let me know if you think differently.

Cheers

Lib needs to be there - people shouldn't need to have a CS compiler to use Spine.
