chore(infrastructure): Add validate-commit-msg hook

* Auto-installs a `commit-msg` hook when `npm (i|install)` is run.
* Ensures that the commit message is formatted properly according to
  angular's conventions.

Note that as outlined in the `helpMsg` key, this can always be disabled
by passing the `--no-verify` option to `git-commit`.
