- Added both schemas to CI tests
- Fixed an issue where delete all would fail

- Fixed an issue where null foreign keys were not being set as valid in relationships
- Fixed an issue where you could not insert/update/unpsert a table with only a primary-key
- Fixed caching for upsert (previously too aggressive, and missing some cache keys)
- Fixed caching for MySQL queries without return columns

- Fixed several template generation failures
- Fixed several struct randomization issues for testing
- Fixed several lint errors in the generated code
- Force MySQL to use time.Time parsing (see README for requirements)
- Recognize "_uuid", "_oid" and "_guid" (in addition to "_id") as suffixes to be deleted when naming relationships
- Refactor the one-to-one relationship, duplicate rather than using clever sub-template abstraction
- Removed reflect helpers (GetStructPointers/Values) for optimized versions (PtrsFromMapping)
- Removed checks for rows affected since they're unpredictable
- Removed unused variables from text_helpers
