Setup for new Nano WiReach board on 5.2 version

Added setup for new Nano WiReach board on 5.2 GEVCU version.  Retained
old setup for 4.2 under “w” command and used “W” for new version.

Added latest firmware for WiReach board to utilities and some serial
connection samples that allow multiple commands to the board.
WiReach Setup moved to GEVCU.ino setup()

That’s about it.
New Wireless Commands and Initialization

1. Changed GEVCU.ino where initialization of WiReach chip only occurs
if EEPROM init is run.

2. Solved the longsuffering ongoing problem of ICHIP not loading
parameters when the program first comes up.  Added a loopcount variable
to Serial Console.  At loopcount == 10,000 it forces ICHIP to load
parameters.  The website now comes up wiht all parameters loaded -
every time.

3. Added WIREACH command.  WIREACH=anycommand will send At+ianycommand
to the wireless device.

4. Added SSID command.  SSID=whatevername will set the SSID of the
wireless device to “whatevername”.
Active immediately.

5. Added IP command.  IP=192.168.3.10 will change the current IP number
to 192.168.3.10 - active immediately.

6. Added PWD command.  PWD=secret will change the password of the GEVCU
configuration pages to “secret”.

The WIREACH command allows you to send any command, so the remainder
are to some degree redundant.  But they are quick and somewhat
intuitive.
Added CANCEL to loopcount

Once Serial Console has forced ICHIP to load parameters, it sets a
CANCEL bool to discontinue the count.
