* Drop support for checkpoints
* Deprecate .flush()
* Remove .begin/.commit
* Remove rollback() and deprecate save/autosave/reset()
There's no need to commit anymore, as the Rust code is handling
transactions for us.
* Add safer transact() method
This will ensure add-on authors can't accidentally leave a transaction
open, leading to data loss.

- notetypes are fetched from the DB as needed, and cached in Python
- handle note type changes in the backend. Multiple operations can now
be performed in one go, but this is not currently exposed in the GUI.
- extra methods to grab sorted note type names quickly, and fetch by
name
- col.models.save() without a provided notetype is now a no-op
- note loading/saving handled in the backend
- notes with no valid cards can now be added
- templates can now be deleted even if they would previously
orphan notes
a number of fixmes have been left in notes.py and models.py
