Bug fixes / Added features in version 1.51 compared to 1.50

1. Fix of the consumption calculation errors
Some errors were found in calculation of cost for energy consumption that were fixed.

2. Added room temperature feature
Room temperature is obtained from the DigiLine temperature sensor.
If there's one radiator in the room , then only from this radiator.
If there's more radiators in the room, then from the first added radiator to the room (in the rooms and devices management).

Example, if you add radiator # 5 to the room and then radiator # 1, the room temperature will be always obtained from radiator # 5 . You can swap them later in the in the rooms and devices management if you want to use other radiator for measurements
