Add a priority field to EMailFormatterExtension and EMailParserExtension class structs. Extension classes can then explicitly specify a priority with respect to other extension classes with the same MIME type, so that the order of extension registration doesn't matter. Priority field defaults to G_PRIORITY_DEFAULT. Built-in formatters and extensions will use G_PRIORITY_LOW. We can get more sophisticated with priority values if we need to, but this should suffice for now.
