Adds Ctrl+<number> hotkeys to color hex tile where cursor points to.
Pressing color hotkey on the same hex removes it, Ctrl+0 removes all colored tiles.

Point is to highlight any kind of service-reach or future-placement hexes easily,
or just doodle on the map at your leisure while drones and colonists are hard at work.

List of drawing crayons:

- Ctrl+1 - █ Crimson [e6194b]
- Ctrl+2 - █ Maroon [800000]
- Ctrl+3 - █ Royal Blue [4363d8]
- Ctrl+4 - █ Navy Blue [000075]
- Ctrl+5 - █ Chateau Green [3cb44b]
- Ctrl+6 - █ Teal [008080]
- Ctrl+7 - █ Green [00ff00]
- Ctrl+8 - █ Black [000000]
- Ctrl+9 - █ Mint Green [aaffc3]
- Ctrl+0 - mass-eraser (careful, removes all paint marks on the map!)

They all look kinda neon too.
Keys can be redefined via the usual options menu.

Why these colors? - picked at random to be somewhat distinct.
Why hexes? - easier to mark game-related things with these.
Why paint? - placing stuff on plain ground within unmarked reach of multple things is hard.
Why Marx? - wanted to spell "❤ marks" but thought to shorten it a bit.

Checked to be compatible with Gagarin / Space Race update 237,920, and probably later versions.
