Add MQTT state field requirements to wiki for HA

[ronschaeffer]

Please add to the wiki which MQTT state fields are required for optimum integration with Home Assistant.

I would create a PR, but I'm unsure what it correct. I'm currently using the following, which appears to work properly.

"group_state_fields":[  
      "state",
      "brightness",
      "saturation",
      "color",
      "mode",
      "color_temp",
      "bulb_mode",
      "computed_color",
      "effect",
      "device_id",
      "group_id",
      "device_type"
   ]

There should be defaults for this setting, which is why it's not documented on that wiki article (note that they are documented on the README).

However... just tried clearing my config, and there were no defaults set. This was a regression introduced by this commit, which cleaned up some internals.

Will push a fix.

Will be fixed in 1.9.1.

Fixed the bug and added a line about making sure that config is set on the wiki page.

Thank you for reporting!

That was quick. Thanks!
