Converts project from Coffeescript to vanilla Javascript

I was trying to sort out a couple of other issues but coffeescript was hindering me. Done this PR to try and move things along.

Created a script to convert files in app and src directories. 
Converted files. Changed gruntfile to remove coffeescript stuff and fix build. 
Removed all references of the coffeescript build directory from code. 
Tweaked a computed property which was converted wrong.

Everything seems to be working in the examples.
Likewise. I think this is because its indented. Will recheck my code and regen.
