move all test data inside the inlined ufoLib/test modules, and install them

Since the test suite is inlined, it makes sense to also have the test data installed alongside the test modules.
So all the content of the two top-level folders Data and TestData is now placed inside Lib/ufoLib/test/testadata.
The MANIFEST.in has been adjusted accordingly.
The `install_package_data` in setup.py ensures the package data specified in the manifest is installed with the package.

This way anyone who installs ufoLib (even the wheel from PyPI) can run the test suite with `pytest --pyargs ufoLib`.
