Post total wh to Emoncms instead of watt-seconds

[glynhudson]

Currently the OpenEVSE posts watt-seconds to Emoncms. IMO this is particular unuseful and probably my mistake!

I propose changing to post total accumulative wh

This Input can then have a 0.001 scale applied in Emoncms input processing and logged to a Feed using wh_accumlator Emoncms input process. This will ensure that even when the OpenEVSE EEPROM is erased and the total wh is lost Emoncms will preserve the value i.e wh_acculoator Emoncms feeds cannot go down, only up!

Here is a device template for the new device module (now live on Emoncm.org and emonPi) for the OpenEVSE to automate logging inputs correctly to feeds:

This is kind of a breaking change, may be best to add a #define to enable the old behaviour or add the wh as a different name

Indeed, it's a breaking change, however, posting watt seconds was so unuseful I doubt anyone will have made use of it. I tried to but in my experience, the large numbers it generated seemed to crash Emoncms. Probably an overflow issue. I can't see anyone wanted to revert ws. My vote would be just to get rid of it for good avoid adding complexity. What do you think @chris1howell?

Yeah, we were not using it for anything. I do not see an issue with the change.
