Update dependencies

A lot of our runtime dependencies are out of date. Preferably we could also update our development dependencies if it isn't too difficult.

I just updated dependencies on dev which has now been merged into master. Should be reflected next time it syncs.

Ah okay, didn't realize that. Thanks.

I'll close this if/when Gemnasium is happy.
