Extracted checks into a tools directory.

Having the checks duplicated between .git-hooks and .travis.yml was a
recipe for them to diverge eventually. This is somewhat tidier, and
creates a clear convention for any future tools-like scripts.

I didn't do the same to install steps, as they're a lot more sensitive to the
specific environment - Travis requires different things from Github, which
requires different things from CircleCI, which requires different things from a
local environment.
