[Freeciv-Dev] (PR#8953) rules-set for specials

["Marcelo Burda" <mburda@xxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=8953 >

Separate Special from terrain.
I propose there to create new rules-set for special.

We can begin with the more simplest specials, to then  try to include
all ones. rivers!
finally we can move vegetate(Forest and Jungle [#3762]) and Relif[#8935]
to specials too

First proposal of syntax and semantic by a sample:

; a terrains can  get a single special of a special set
; the special will be put on map by generator in order of set defined
;if a special is a condition for a another this will be form a set
defined befor.
;
; allowed = simle boolean condition && / || operators 
;                 Terrains_has(_not)_flag(Name)
;                 Terrains_has(_not)_special(Name)
;                 Terrains_has(_not)_name(Name)
;
;flag = 
;           Trigger_on_touch(Action) this special trigger a action
;Action
;            “Get Hut” special is destroyed, player can get some gold,
tech or be attacked 
;
