Some minor changes to the interface.

- Simplified logger to accept only a string, not a variadic list
  of args like printf(). This can still use some improvement,
  but now it is easier to use from other languages.
- Fixed some misuses of the logger (wrong types etc)
- Renamed some constants
- Fixed some typos in comments.
