Update terraform-fmt to match terraform-validate (#46)

This PR updates the `terraform-fmt` hook as follows:

1. Run with `-diff -check` so the differences are printed, rather than made on disk.
1. Instead of exiting on the first error, save the exit codes, and print out all `fmt` errors before exiting.

These changes are very similar to gruntwork-io/pre-commit#45.
