Servo signal (#227)
Prepping for version 4.1

SERVO_SIGNAL definition in EXRAIL
SERVO_SIGNAL(vpin, redpos, amberpos, greenpos)

use RED/AMBER/GREEN as for led signals.

* SIGNALH, ATGTE, ATLT

UNTESTED

* Automatic ALIAS(name)

and _ in keywords

* EXRAIL FORGET current loco

* EXRAIL </KILL ALL>

* EXRAIL VIRTUAL_TURNOUT

* Cleanup version.h

* Update version.h (#223)

Rewrite & Updated the 4.0.0 Section

* </KILL ALL> fix

* Incoming LCN turnout throw.

* KILLALL macro

and DIAGNOSTIC messages when KILL command used.

* EXRAIL PARSE

* Rebuild throttle info getters

UNTESTED... create different methods to obtain throttle info without being withrottle specific.

Also implements turnout description of "*" as hidden.

* J command parsing

JA JR JT commands parsed
EXRAIL sets hidden turnout state
HIDDEN description macro
Turnouts hidden flag bit
UNO seems OK, MEGA UNTESTED

* Assist notes draft & syntax tweaks

* Throttle notes

* uno memory saver

* JA JR and <t cab>

* Subtle corrections

* Update version.h

* I2C code corrections

Corrections to I2C code:
1) I2CManager_Mega4809.h: Correct bitwise 'and' to logical 'and' - no impact.
2) I2CManager_Wire.h: Ensure that error codes from Wire subsystem are passed back to caller in queueRequest().

* RAG Ifs and cmds

* IF block perf/memory

* Allow negative route ids.

* correct GREEN keyword

* Update version.h

* myFilter auto detect

* Update version.h

* fix weak ref to myFilter

* ACK defaults now 50-2000-20000

* Update version.h

* Improved SIGNALs startup and diagnostics

* Update IO_PCA9685.cpp

* Allow turnout id 0

* Position servo pin used as GPIO

* NoPowerOff LEDS

* CALLBACK parameter optional for Write

* WRITE CV ON PROG <W CV VALUE>

Callback parameters are now optional on PROG

* Updated CV read command <R cv>

Equivalent to <V cv 0>  uses the verify callback.
