Controller repo finally added to travis

[Fraser Scott]

Passing, but the tests suck. The controller code needs to be refactored quite a bit before tests can be written properly, otherwise you'd just end up writing integration tests in Go that are almost identical to the Bats ones in the admin repo.

Anyway, at least it's a start. I'm going to focus on the SSH stuff again now, want to make some actual progress with something functioning.
