add heat pump dhw/disinfectduration (0xEA offset 15), #3278

Browse Source 
The DHW thermal disinfection duration (time allowed to reach the
disinfection temperature; on timeout HPC4x0 reports A01(5284)) is
sent in UBAParameterWWPlus 0xEA offset 15 in steps of 10 min, but was
not decoded. Add boiler/dhw/disinfectduration for heat pumps,
readable and writeable, range 120-240 min as on the HPC410 menu.

Tested on a Bosch Compress 3400AW with HPC410: changing the duration
on the controller writes 0xEA offset 15 (150 min -> 0F, 180 -> 12),
and writing 0B 08 EA 0F 11 from EMS-ESP made the HPC410 menu show
170 min without errors.

- new Application Setting "Automatically check for firmware updates", off by default. When enabled EMS-ESP asks emsesp.org for the latest version once a day on its own, otherwise it only asks when the WebUI wants to show it, so an unattended system never contacts emsesp.org
- Automatically check and convert older 3.8.x filesystem to the new 3.9.0 format
- heatpump pool: `poolon` (switch, 0x48A), `hppoolon` (pool heating active, 0x488), MP100 `poolshuntset` (0x5C4) and `poolrequest` (0x5BA), shorter pool names
