fire-dom-events and icon color fix

I added the fire-dom-events as an option for tap_actions so you can call browser_mod for example when tapping a tile.
Example config:

                        tap_action:
                          action: fire-dom-event
                          browser_mod:
                            command: popup
                            title: 'My Title'
                            card:
                              type: 'custom:mini-graph-card'
                              entities:
                                - weather.weersverwachting

I also added useRGB in the config for the card, it is an addition on the useBrightness and useTemperature to disable the change of the icon color based on the light. I hope this fixes issues where people got i white icon somehow while brightness and temperature are off.
