This fixes some bugs from v3.2:

Heatpump stop responding to heishamon on v3.2 after heishamon started. Heatpump power cycle needed
Rules edit page empty and no save button in certain situations
Fixing rules for K/L extra topics
Also, the version is now visible in the mqtt stats topic.

What is new for release 3.2:

Opentherm support for Heishamon boards with opentherm option. Data via MQTT readable (receive from thermostat) and some are writable (send to thermostat). Internal rules are also working for opentherm so you can combine heatpump topics with opentherm values as actions etc.
New data block for heatpump types K and L support which for now only includes new heat/cool/dhw power consumption/production values with more precision. These new values are in XTOP shown on the webpage and in /extra/ topic in mqtt.
Rename 'Energy' to 'Power' for the heat/cool/dhw consumption and production topics. Remember to change this into your home automation tools
New heatpump type are recognized (TOP92)
Add weekday and minute to rules engine
