* web: fix rfb node generator syntax, do not send as basic settings

* ha: allocate discovery object later

- use setOriginalsFromValues function right after elements had changed and
**only** with those elements
- add checkbox handling to setOriginalsFromValues to match hasChanged
- apply hasChanged after value is set to refresh originals after saving
- change parts that already set 'original' attribute manually

This was sort-of broken, because original attr never worked as intended. 
Also fix possible OOM for large WebUI images, since sending full config each time means that we need more memory to buffer and parse it.

* Fixed small esthetic problem

* Changed to legend

Amend #1843 , since we have updated ESPAsyncWebServer
Fixes (again) #1300

Gather WS debug messages in a buffer and flush every N times
info,keys,crash actually output data now

- update every dynamicjsonbuffer with fixed size constructor argument
- change to ws callback registration to use a class builder (just cosmetic)
- test multiple ws data callbacks for each module
- remove some of the static strings in favour of ws data callback
- improve sensor ws callback data size, remove duplicated strings
- use static buffer in wsDebugSend
- postpone wsSend until loop, implement wsPost to allow other modules to queue message callbacks. remove Ticker based ws callbacks for data
- update WebUI files

* add CCT support for 2 channel boards

* update webinterface description

* add 2 channel CCT to homeassistant and domoticz

* remove domoticz two channel cct support.

Allow defining custom device name for alexa integration, other than hostname.
Still uses hostname as a fallback.

- remove optional RFRAW_SUPPORT
- enable module when RF_SUPPORT=1, optionally enable RCSwitch
- reorder ifdef checks to treat RFB_DIRECT and old RF_SUPPORT the same
- rename RF_PIN to RFB_RX_PIN
- depend on RF_SUPPORT instead of ITEAD_SONOFF_RFBRIDGE
- runtime TX & RX PIN setting

* Add "Enable Thermostat" switch

* Add heater/cooler thermostat mode

1. Add thermostat to the espurna_modules in progmem.h
2. Add thermostat to webui, gulp, html, js.
3. in general.h MQTT_USE_JSON returned to 0 by default and 1 if thermostat enabled.

* Simply print timestamp for supported destinations
* Update ws destination to support 'prefix' sub-key
* Avoid void casting in telnet module
