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

* Changelog

* Improve sing screen and redesign pause menu

- Fix jumping to the old pause position after restarting or skipping a song in vocals mode
- Keep name and avatar hidden for players without a valid profile
- Show the placeholder avatar for profiles without avatar image
- Hide player information and rating popups during the start countdown
- Fix pause select slides not being shown or hidden
- Show "no more songs" only when Ctrl+S is pressed
- Select "Continue" when opening the pause menu with Escape
- Darken the game behind the pause menu
- Pause buttons as vertical list with icons, hidden buttons leave no gaps (visible buttons are placed in the slots of all pause buttons)
- New PauseButton skin with rounded corners for wide buttons, used for the pause buttons and the vocals volume selection
- Larger pause title centered above the pause panels
- Info panel with cover, title, artist, song progress and player scores
- Vocals volume selection with icon and centered caption in the full width of the info panel, showing five values
- Pause panels and icons are animated together with the pause buttons
