Diplomacy colors

[temple]

Add a button to toggle between normal and "diplomacy" colors:

• When playing, players are colored according to your stance towards them: green are allies, yellow are neutral, red are enemies, and blue is you.
• When observing, players are colored according to their team. (e.g. in a 4v4 one team could be blue and the other red.)

Implement basic color editing in the options page and use it for the diplomacy colors, refs #4747, rP21107.
Update the RangeOverlay config option only when the options dialog was closed, not each turn, refs rP19519.

In 23091:

Make options page agnostic of session page and implement RangeOverlayManager GUI class, refs #5387, #4747.

Avoids further session commits that missed to keep options.json session code in sync,
enables use of anonymous or object owned config callback handlers and
encourages session developers to make the GUI more reactive to changing options.

Update RangeOverlays when reseting to default, and update
RangeOverlays of selected entities upon closing the page too (not only hotkey).
