QOL Entity Drawing wrt Zoom

[BenSmithers]

Users should be able to see different amounts of detail depending on the zoom level.

• Users should only see a single entity drawn on a hex at low zoom. Preferentially a settlement
• Users should see up to seven entities on a hex at a higher zoom level.
• Users should be able to see even more at an even higher zoom level.
• After zooming in far enough, Entity icons should stay the same size.
• Users should be able to configure the zoom levels when this change happens, OR MultiHex should use the screen size/resolution to decide appropriate zoom levels.
