Small improvements for 3 screens (#934)

* Improve profile and player selection screens

- Ask before deleting a profile, Delete only removes a character while editing the name
- Ask to save or discard unsaved profile changes when leaving the profile screen
- Restore the previous name with Escape and prevent empty profile names
- Stop the webcam when leaving the profile screen and discard snapshots on avatar change
- Show inactive profiles dimmed in the profile screen
- Play the missing mic/profile warning each time the player selection is shown
- Fix crash when clicking a profile after removing a player with Delete in fast selection
- Keep the duet part selection when profiles are reloaded
- Only save the player number when it has changed

* Use party mode selection look in statistics screens

- Tiles and selection use the ButtonTile skin like the party mode selection, the selected tile uses the selection color of the skin
- The detail list uses the CoverTextBackground skin, inner cards and row stripes the ButtonTile skin
- More space between the title and the columns of the best list
- Show the date in the recently sung list left aligned inside the list
