Colors are not restored on exit

[mnml]

On my specific setup (using WSL and the Windows Console), the colors are changed after exiting the game (note the brighter green and white in the last image):

I can think of two possible solutions:

1. Saving the color values before calling init_color in colors.c, and restoring them on exit.
2. Not using init_color at all, instead leaving the colors up to the player's terminal settings.

Also, I noticed the rat in the middle image is white, even though it's set to COLORS_RED in the code:

hag/src/enemy_rulebook.c

Line 23 in c41af1b

rulebook[book_length].pic = 'r'|A_BOLD| COLORS_RED;

I suspect the A_BOLD is somehow responsible (maybe causing it to use a different color value?).

I'd be more than happy to make a pull request implementing whichever solution is deemed more preferable. I'm partial to option 2, since it would probably fix the enemy color bug, while also allowing players to customize their colors if they find the current ones undesirable (e.g. due to color blindness).

Option 2 sounds good to me.
