Release of first beta for 1.14.2

This is a small bugfix release, mostly to ensure that people can compile
Freeciv properly. We have, however, added some game balance adjustments
that will hopefully make the game more interesting.

WHAT'S CHANGED SINCE 1.14.1
 - important compile fixes for some platforms
 - game balance adjustments:
        x all buildings except wonders and space parts 30% cheaper
        x some wonders cheaper: Colossus, Copernicus, Isaac Newton's,
          King Richard's, Oracle and Shakespeare's
        x submarine has more attack and movement, and costs less
 - reputation recovery fixed (now much slower)
 - a few other minor bugfixes

Please try it out and report any issues. This will hopefully be a small
and quick beta, so it will not be reported widely. All the more reason for
_you_ to test it!
