tap_action, color_off, state style, more-info

Lots of breaking changes in this release but a big push towards alignment with other standards and some cool new features. Great work @RomRider!

Breaking Changes

• color_off is now deprecated, use state instead if you want to redefine the color when off
  Instead of:

    - type: "custom:button-card"
      name: Switch
      entity: switch.main
      color: red
      color_off: green

  Use:

    - type: "custom:button-card"
      name: Switch
      entity: switch.main
      color: red
      state:
        - value: 'off'
          color: green

  Or:

    - type: "custom:button-card"
      name: Switch
      entity: switch.main
      state:
        - value: 'off'
          color: green
        - value: 'on'
          color: red

• default_color is deprecated as it seems redundant with color (when light is not rgb). For rgb light, you can still define a specific color for the off state for example.
• service has been deprecated in favor of tap_action, see below
• action has been replaced by tap_action to mimic the default button card and allow for future options like hold_action
• more_info renamed to more-info, more_info still works
• service now takes the full service name light.turn_on
• Add default entity icon support, Fix #53, add show_icon to decide whether to display the icon or not

Others

• blink animation support, see examples
  
• tap_action supports navigate. Fix #75 & Fix #31
• Support for style definition in state. Fix #41
• Disable click when not needed
• Refactored the code for faster rendering
• Documentation update
• Fix #71
