Initial import of the WOFF tests, unmodified

Only the generators scripts and resources, not the generated files.
Use os.makedirs instead of os.mkdir

Otherwise, running the scripts out of a fresh clone will fail as it
tries to generate, e.g., AuthoringTool/Tests/xhtml1 without creating
AuthoringTool/Tests first.
Use Behdad's FontTools

The old one is no longer maintained.
