UI

[cptKNJO]

This PR adds the following features:

• Implement component for managing a single setting for a client
  • Setting can be sourced from 3 values: Inherited setting value, server setting value, client setting value
  • If a setting is edited it automatically switches to the server setting value
  • There is a button that switches between different settings values
  • Some settings are "mergeable" - can take values from multiple sources
• Add setting screen when a client is selected showing the different settings areas (File Backup, Images backups, …)
• Add settings to file backups tab
• Implement saving the settings if they are modified

Additional notable differences:

• Avoid double negative labels for form fields
• Break form into smaller forms with their own submit buttons
• Replace toggle for mergeable settings with checkboxes (retains the same functionality with fewer steps)

Looks good, thanks! Changing from the button with symbol to the drop down with more explanations inline seems like a really good usability improvement.
Same for the bigger sections for the settings that can be combined (though the ultimate improvement there would be to have some editor).

I'm sorry for commenting here, but I'm not sure where I should honestly.

My server doesn't look like this at all. How do I get this nice dark theme and the left navigation. I just have the all white experience like shown at http://www.urbackup.org/. Is there some toggle I'm missing?

Happy to move this elsewhere, but this is the only place I've seen the UI look like this.

This is a woek in progress and not in use by prod versions.
