Set appropriate button input mode on BL KM200 when switching groups

When switching to temperature control group the button input mode must be set to 65/heating pushbutton

implements #18333

@chhitz in the ticket Wolfgang writes that moving the device to the heating group should set the button input to 0/standard, I do not know if he rather meant "when switching to any group except for temperature control", right now I implemented it without limiting it to the heating group. Please let me know if that's OK or if more adjustments are required. Also see my comment to you in the ticket.

Build finished. Tests FAILED. Build results available at: http://dsjenkins.cloudapp.net/jenkins/job/dSS_MR/1092/

As I understand the differentiation between TemperatureControl and not-TemperatureControl is correct. The UI does only allow Heating and TemperatureControl.
