Upgrade meteor to 1.2-rc.4 and package versions

The new version of meteor speeds up the reload cycle, which is super
valuable during the development. I also removed the "imply-everything"
"meteor-platform" package in favor of a more fined-grained package
selection.

This version also introduces ES6 support with transparent babeljs
transpilation. Most features are enable (with the notable exception of
ES6 modules) and this commit started to use them in places where a XXX
comment suggested it.
