Add support for new accessories and update mechanism

[tonysprenk]

HAA has a few new accessories and an update mechanism where it is possible to add a switch to an accessory to enter setup mode and to initiate an update. Would be nice to see these features incorporated in the JSON configurator.

I would also add, simple to put in the Json for who knows it, the hostname feature just added in the last version ;-)

Will be there support for SOnoff 433 RF bridge and also for PIR and window/door senzors?

+1, I personally use them for every HAA device:
{"1":{"s":[{"a":1}]}},{"1":{"s":[{"a":2}]}}

They should belong to General config section.

I would add to the list the http call possibility as in this example posting on influxdb temp and humidity data, very useful to my opinion.

{"c":{"l":13},"a":[{"t":22,"n":1,"j":10,"y0":[{"0":{"h":[{"h":"influxdb.lan","p":8086,"m":2,"u":"write?db=haadb","c":"sensor,device=office value=30"}]},"v":30,"r":0}],"b":[]}]}
