Revised Ver By Reason
6/21/13 20b3 Scott Rubin fixed LCD display bugs with RTC enabled
6/25/13 20b4 Scott Rubin fixed LCD display bugs, CLI fixes, when RTC disabled
6/30/13 20b5 Scott Rubin added LcdDetected() function, prevents hang if LCD not installed
7/06/13 20b5 Scott Rubin rewrote power detection in POST function for 1 or 2 relays
7/11/13 20b5 Scott Rubin skips POST if EV is connected, won't charge if open ground or stuck relay
8/12/13 20b5b Scott Rubin fix GFI error - changed gfi.Reset() to check for constant GFI signal
8/26/13 20b6 Scott Rubin add Stuck Relay State delay, fix Stuck Relay state exit (for Active E)
9/20/13 20b7 Chris Howell updated/tweaked/shortened CLI messages
10/25/14 Craig K add smoothing to the Amperage readout
3/1/15 Craig K add TEMPERATURE_MONITORING
3/7/15 Craig K add KWH_RECORDING
