IW: Update var names in make file
IW: Don't include the Traceur runtime in dev

I was unable to get the Traceur runtime to be included into the build without
messing up the source map line numbers. This commit includes the runtime
in a different script tag for development. It also includes the runtime
in the compressed version of the tangram. Users of the compressed
version should not noticed a difference.
IW: Hack to offset source maps with Traceur
IW: Update browserify and fix everything
IW: Remove module to rewrite source maps
switch Utils to new ES6 import style
Merge branch 'traceur' into camera-es6
