[Freeciv] rndCiv v.0.7 - now with Unit grafix

[banjo <banjo@xxxxxxxxxx>]

hi all

Ok, rndCiv 0.7 is up on

     http://banjo.actrix.com/code/rndCiv/

This version adds unit graphics for over 100 new units.

I have been running randomly created rulesets (in freeciv 2.0.7), and 
things mostly work, except for...

* sometimes the server just crashes, dunno why, am investigating

* the general_effects has these warnings
  Player-ranged effects are only supported for wonders.
  Surviving effects are only supported at world range.

  spec_gate[0] couldn't match special "Rail"
  spec_gate[0] couldn't match special "Oasis"
  spec_gate[0] couldn't match special "Silk"
  spec_gate[0] couldn't match special "Iron"
    maybe im not using these correctly, they'd be nice to have though

  unknown effect type: "Trade_Bonus"
    it is mentioned in doc/README.effects
    it's a useful effect
    i can replace it with "Trade_Per_Tile", but that's not so good

* old effects that are gone
  "Make_Content_Pct"
  "Heli_Defend" - it should be there
  "Unit_Move" - nice for elves to move faster in forests
  "Capital_Exists" - nice to have a fallback
  "Pollu_Adj"
  "Sea_Vet_Combat" - why not?, Land_Vet_Combat exists
  "Barb_Defend"
  "Sea_Recover"

Wishlist
  Units:
    - Can we have a flag that hides a units Nationality,
      or gives it a pirate/barbarian flag, like in Colonization
    - can we divide up the Diplomat flag, it'd be nice to have
      specialty units that can do subsets of what a diplomat can do
       ie. InvestigateCity, PoisonCity, BribeCity, SabotageCity
      (i'd like BlackOps to InvestigateCity, PoisonCity, SabotageCity )
    - a unit flag that lets the unit steal gold from a city
    - Can the Spy flag *not* have to be with a Diplomat flag
    - Im not sure exactly what the Nuclear flag means, i'd like
      Fusion Tanks to pollute whenever they fight.
    - Unit type Hover, for Hovercraft & Hovertanks, can travel over
      water, and flat land, & roads
    - Unit type Rail, can only travel over Railways

  Buildings:
    - Trade_Bonus
    - Sea_Recover
    - Heli_Defend
    - Barb_Defend
    - Sea_Vet_Combat
    - Unit_Move
    - Player-ranged effects allowed for all building types

------------------------------

Anyway rndCiv mostly works, it provides a nice stress test for the
freeciv server, and exposes assumptions in the freeciv ai.

The rulesets need lots of tuning, and any help would be appreciated.
