Expose load_current_load_order_state() via GameInterface

Significant changes include:

- The logging interface has changed, a callback can now be set
  instead of an output file and verbosity, giving clients more
  control.
- DatabaseInterface::EvalLists() has been removed.
- SimpleMessage now has a condition field.
