Zachary Wasserman 35806f1442 Separate tables from data migrations (#745)
This PR separates the table migrations from the data population migrations. Table migrations run before data migrations.

Now, we have the ability to create the database tables without populating them with data. This can be useful for running "unit" tests against a MySQL store that doesn't have any pre-populated data. When performing real migrations, or for more "integration" style testing, the data migrations can also be executed.

Note there are some special cases that must be observed with these migrations, and the README is updated to reflect those.
