Address the inconsistent naming of smart modules by removing all "Module" suffixes and aligning filenames with class names. Removes the casting of modules to the correct module type now that is is redundant. Update the adding of iot modules to use the ModuleName class rather than a free string.
This improves the temperature control features to allow implementing
climate platform support for homeassistant.
Also adds frostprotection module, which is also used to turn
the thermostat on and off.
