[Freeciv-Dev] [Patch] Watchtower v3

[Bert Buchholz <bertbuchholz@xxxxxx>]

So, this is the 3rd version of the watchtower-patch.

Features:
Nothing new really...

Up to now, following events regarding watchtowers are handled (there may
be more to handle which I didn't see):
- A fortress is pillaged (vr reduced)
- A town is built upon a fortress (vr reduced)
- A unit steps into a fortress (vr enhanced)
- A unit steps out of a watchtower (vr reduced)
- The necessary invention is made (all units inside fortresses get
  enhanced vr)
- A fortress is built (all units on that tile get enhanced vr)
- A unit getting upgraded inside a fortress (mostly not changing)
- A unit is created on a fortress, for example barbarians, or a unit is
  being bribed (vr enhanced)

  *New*
- A unit gets killed inside a fortress or is disbanded (handled with the
  same function remove_unit_sight_points()) (vr reduced)
- A sentried unit inside a fortress get awaked, if an enemy unit moves
  into his visionrange.
- Patrol is canceled, when a unit is in a fortress on a patrol and sees
  an enemy unit.
- Exploring units inside fortresses are also taken into account

I made the values watchtower_vision and watchtower_extra_vision global
(inside the game struct) and made them changeable by wtowervision (def:2
min:1 max:3) and wtowerevision (def:0 min:0 max:2). I also made the
descriptions, I don't know if it's understandable for only-players.

Of course I made these values load- and saveable (is there such a
word?). I hope I did this correctly, it works here w/o problems, so I
hope for the best. :-)

Again, I attached a(nother) savegame, playername is swk, move on a bit
in time and have a look. You can also change the values inside the
savegame with an editor and see the effects.
