Subject: [PATCH 21/26] Fix: Poor contrast in cargo dest flow legend window
 cargo labels.

Select foreground colour depending on the brightness of the background.

Previously all cargo labels were rendered using black text, even
the background cargo colour was dark/black.
As an example: FIRS coal was black text on a black background.

Subject: [PATCH 23/26] Change: Modernise music control logic implementation
 (#6839)

Rewrite of almost the entire music control logic to a more modern style, hopefully also easier to understand. The old playlist handling made it look like arcane magic, which it doesn't have to be.

- Playlists are now stored in std::vector of objects instead of arrays of bytes with magic sentinel values, that need to be rotated around all the time. Position in playlist is stored as a simple index.
- The theme song is now reserved for the title screen, it doesn't play on any of the standard playlists, but is still available for use on custom playlists.
- When the player enters/leaves the game from the main menu, the music always restarts.
- Playback state (playing or not) is kept even if music becomes unavailable due to an empty playlist (or an empty music set), so it can restart immediately if music becomes available again.
- The shuffle algorithm was changed to a standard Fisher-Yates.
- Possibly better behavior when editing a custom playlist while it's playing.
- Custom playlists should be compatible.
- Framework for supporting custom playlists with songs from multiple music sets.

Subject: [PATCH 24/26] Add: Hover tool-tips to cargo dest flow legend window.

This is to improve the usability of the window.
The two-letter abbreviations are not always clear, in particular
when using a large number of cargoes.
The company colours can be ambiguous when there are a large
number of companies.
