From Steve Karg:
The ConfirmedEventNotification decoding was only done as far as context tag 8, so BACnetNotificationParameters 9, 10, and 11 displayed as malformed packet. Added context tag decoding for BACnetNotificationParameters 9, 10, and 11. Added missing breaks in several switch statements. Corrected some dissector aborts. Added several new enumerations from the latest BACnet 135-2008 standard, and updated the list of BACnet Vendor IDs. svn path=/trunk/; revision=27527
