Update freeciv to 2.3.2

There are many many changes since 2.2 including:

   A new program has been added to the Freeciv suite: 'freeciv-modpack'.
   This makes it easier to download and install add-ons ('modpacks':
   rulesets, tilesets, etc) to the right place; you can enter a URL,
   choose an add-on from the list, and the tool will install it to the
   correct place for this version of Freeciv to use it.

We also include a security fix.
