Alex Hall	42afb17e36	(core) Run and test imports only in Python 3, upgrade openpyxl, fix weird date handling ... Summary: Python 2 only needs to be supported for the sake of old documents and formulas. This doesn't apply to the separate sandboxes that parse files for imports. Using Python 3 only allows using newer libraries and library versions. In particular, the latest version of openpyxl doesn't support Python 2. This will also make it easier to make other similar changes in the future, such as replacing messytables with a modern library.

Within Python, a module used by all imports will raise an error in Python 2. Python unit tests of imports are now only run in Python 3, using the `load_tests` protocol of `unittest`. Test Plan: Mostly existing tests. Added another strange date to the Excel fixture.
