The "better patch" would be more efficient, but at data rates this low "easier to read" wins.  Merged.

A better patch would be to match string that start with "!" and have lexer->inbuffer + 3 start with VDM or VDO, but the attached patch gets all the talkers I saw yesterday in the USCG NAIS feed.  It really shouldn' matter which talker sent a VD[MO] message.

Also needed is a patch to  gps2udp.c.

Talkers:

- AB - Independent (???) AIS Basestation
- AD - Dependent AIS basestation
- AN - AIS ATON (aid to navigation)
- AR - AIS Receiver
- AS - AIS Station - "limited" basestation ??
- AT - AIS transmit station
- AX - AIS repeater
- BS - Basestation (not in NMEA 4.0)
- SA - Physical shore AIS station
