Fix transmitting to match expected format from EmonHubOEMInterfacer
(also matches how transmission has been done before and works with
emonglcd)
Remove verbose mode and associated Serial.prints to get more room in
flash. Verbose mode is spurious as config changes can be verified with
'l' and 'L' options, and was disabled by default. Without removing these
there was no room in flash for the code. Consideration could be given in
future to make the help more terse and reducing the large amount of
Serial.prints uin the code to gain further space

Format temp and vrms to .2f
Allow emonPiLCD1.py to work with both emonlibCM and DS firmware
