Thermostat command classes

[Ittiz]

There are some command classes that are in Open-z-wave but not in Domoticz. I'm able to pass them to a dummy switch using a back door lua parser route, but it'd be nice if these worked. On a side note, I don't have a compiler so I can't add these myself. These are the command classes:

0x42 (THERMOSTAT OPERATING STATE) -- Basically whether the the thermostat is calling for heat, cool or just Idle
0x45 (THERMOSTAT FAN STATE) -- If the central air fan is running or not
0x87 (INDICATOR) -- I'm actually not quite sure what this does, but Domoticz doesn't know either.

I would be glad to see your LUA, if possible

I would like to survey this state too.

I have added support for reading these two states. The code has been merged.
