More robust removal of CHECK and IDENTITY properties when declaring output table.

        I see what happened. I needed to create BigAutoField and BigIntegerField classes since Django still doesn't include them yet, and the strings returned by my db_type implementations differ from yours.

        Because of this scenario, though rare, I still recommend this change.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
