[test build] Bump some dependencies

https://gemnasium.com/attester/attester

Seems most of the deps are outdated, let's update some of them

However some new versions of the dependencies break the build:

mocha 1.21.4
expect 0.3.1
ariatemplates 1.6.3
send 0.8.1
socket.io 1.0.6

There are more that I haven't tested yet, but have mostly changed the first digit, so incompatibilities are to be expected.
