Backwards compatibility

Hi, I try to maintain backwards compatibility as much as possible, especially in the core API (e.g. the non-device specific parts). But once in a while, I have to break backwards compatibility to fix a bug. If that happens, I'll send a reply to this message with further info. In the last couple of days, backwards compatibility has been broken for this function: * cressi_edy_parser_create: An extra "model" parameter was added to be able to tell the difference between the cressi edy and the zeagle n2ition3.
