Issue 665: pin es6-module-transpiler at 0.3.3 with npm-shrinkwrap

Issue #665: handlebars build is broken with es6-module-transpiler v0.3.4
(also see esnext/es6-module-transpiler#81 and esnext/es6-module-transpiler#82)

This PR adds npm-shrinkwrap.json, to pin dependecies to desired versions (such as 0.3.3 of es6-module-transpiler),

v0.3.5 was just released which should resolve the issue.

Thanks for the PR but I've gone a little bit of a different direction with the fix here.

I've reworked the module packager project so that it supports all of the transpile needs and pined the version to 0.3.3 in there as 0.3.5 looks like it does not have the fix from esnext/es6-module-transpiler#82 compiled in.

The handlebars side of these changes were implemented in 57b4ef0 and you'll need to update your npm dependencies for everything to work locally.

no problem, as long as building handlebars does not fail with obscure error messages :)
