Update to 0.9.10. Changes:
- Ability to use regular expressions in plugins.rules to define
  monitored sources, this can be very useful when combined to file
globing.
- [SPEEDUP] When the "*" keyword is used, the data is passed to the
upper layer without trying to match anything.
- Fix NULL pointer dereference when a rule reference an existing,
  but empty context (fix #226).
- Remove deprecated use of prelude_client_print_setup_error(),
  directly handled via prelude_perror().
- Make the log parser more robust.
