Better support for high pulse count single channel encoders (contributed by Nail Güzel)
Displaying last error in spot value channel (that also makes it possible to send it via CAN)
Added error code when AC current limit kicks in
Added experimental (!) AC_HEAT mode. It is supposed to heat the battery pack by cycling current between two pack halfes. UNTESTED!!
Added possibility to hide parameters (flag hidden) or unhide them (flag !hidden). The flags are stored alongside the parameter values with the "save" command
