(PR#12550) [Patch] Fix H_HUTS

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12550 >

Contrary to what the H_HUTS handicap may say, I always thought the
current behavior was intentional and a bug rather than a feature.  That
is, AI players without H_HUTS won't go after huts AT ALL.  This is a way
to make the easy AI easier.

I don't see why a separate handicap is needed for the ai to have
omniscience about huts.  There's already a handicap that gives the AI
omniscience about the whole map (and this handicap should be checked!);
why should huts not be included in this?

However I think there are two bugs here:

- The knows-whole-map handicap should be checked.
- The H_HUTS handicap should be reversed so the default (human-player)
behavior is without it.  This makes the H_HUTS handicap into a penalty
rather than a bonus (in MoO2 terms it would be a racial characteristic
with a negative value).
