Update dependencies

This bumps Batman's node dependencies to the latest, and vendors new jQuery and QUnits. 

 - upgrade CoffeeScript to 1.6 (through muffin 0.8) and recompile
 - add node v0.10 compat
 - upgrade uglify for minification (and the development removal transform)
 - upgrade q (a library used in muffin)
 - mess with one DOM helper called `innerText` which is now `textContent` to reflect the same behaviour as jQuery (and thus the jQuery adapter). 

@nickjs @kristianpd look ok?
