update dependencies

Review needed

The babel-runtime version is automatically bumped by the preversion script (which invokes the update-babel script). The reasoning for this is explained here: JSRocksHQ/slush-es20xx#30

In other words, better not touch the babel-runtime version here as it will be overwritten before we release a new version of Harmonic anyway.

Got it 👍

It looks like I'll be working overtime the whole week and weekend, so I may not have much time to test things throughout. 😞

Side-note: we have to add - "stable" to Travis' node_js versions and probably remove 0.11.

p.s.: It would be nice to document the new template metadata option before we make a new release.

I've updated most of our dependencies here: d7becc5, 77b6555, 98f4486, f8fcd36, bea91db
We are tracking the update to Babel 6 here: #188
The eventual substitution of the co and co-prompt dependencies is being tracked here: #178
I don't intend to update vinyl-paths until The Great Refactoring™ of es20xx.

I guess this covers it for now. Thanks for noticing the outdated dependencies. 😃

Side-note: I've updated our supported Node.js versions here: c457e01
