Use submodules to reference GitHub repositories

[peterbarker]

Currently we have raw instructions in scripts that git clone random repositories; we should instead have submodules. That will let us reference specific commits that should be checked out, rather than either changing to a branch (which could change), or taking pot luck with the master branch.

seems fair.... unless there's a need to fetch different versions of the same repo for any reason. ..?

Not as far as I'm aware. Additionally, I think the submodule mechanism would probably allow that anyway :-)
