Minor bug-fixes, major additions for users of the sofabaton_x1s integration

For all users:

• Fixed various small layout issues
• Restructured the configuration editor
• What was previously called "Automation Assist" is now called "Key capture". Added documentation for the feature accessible through the UI.

For users of the sofabaton_x1s integration (the "unofficial" integration for the X1, X1S and X2):

• Expanded the capabilities of Automation Assist with a new feature: Wifi Commands.
  Wifi Commands are configured entirely via the UI, and run Actions in Home Assistant when buttons are pressed on the physical remote.

  The sofabaton_x1s integration must be updated to version 0.5.0.
