Calendars titles localization

I'm not a very experienced drupal user but I think there is a problem with the localization of the titles of the calendars. Check the line 389 of the hotel_booking.theme.inc file. The translatable string includes the year, so each time an availability month is added to the data base a new string is created, which needs to be manually translated (August 2010, September 2010...).

P.S: great module anyway!
