- Add a structure describing known models, their features and default settings.
- Use partial screen updates for newer CFA633 versions.
- For CFA533/633 use the same character mapping as for HD44780.
- Fixed a few typos.
- Use C-style comments only.
- Add a warning about the driver being deprecated to CFontz633. Users should
  use CFontzPacket with Model=633 instead.
