comms/direwolf: Update to 1.6

- Really update to 1.6 this time. Changes involved new buld system.
- Corrected non functioning SED
- petted portlint

- Rather than trying to keep a bunch of different platform specific Makefiles in
sync, "cmake" is now used for greater portability and easier maintenance.

- README.md has a quick summary of the process.  More details in the ***User
Guide***.

- "-X" option enables FX.25 transmission.  FX.25 reception is always enabled so
you don't need to do anything special.  "What is FX.25?" you might ask.  It is
forward error correction (FEC) added in a way that is completely compatible with
an ordinary AX.25 frame.  See new document
***AX25\_plus\_FEC\_equals\_FX25.pdf*** for details.

- Receive AIS location data from ships.  Enable by using "-B AIS" command line
option or "MODEM AIS" in the configuration file.  AIS NMEA sentences are
encapsulated in APRS user-defined data with a "{DA" prefix.  This uses 9600 bps
so you need to use wide band audio, not what comes out of the speaker.  There is
also a "-A" option to generate APRS Object Reports.

- Receive Emergency Alert System (EAS) Specific Area Message Encoding (SAME). 
Enable by using "-B EAS" command line option or "MODEM EAS" in the configuration
file.  EAS SAME messages are encapsulated in APRS user-defined data with a "{DE"
prefix.  This uses low speed AFSK so speaker output is fine.
