[Freeciv-Dev] (PR#8754) eff beta6: missing req_type, etc

["Per I. Mathisen" <per@xxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=8754 >

In the default ruleset, there is a effect req_type "wonder". This does not
seem to be supported.

1: for Research Lab unknown requirement type: "Wonder"
(data/default/buildings.ruleset)

Also, civ1 and civ2 rulesets are not updated with the new effects.

Finally, the patch contains this change to civ1 buildings.ruleset, which
should not be in this patch, AFAICT:

 [building_hoover_dam]
 name           = _("Hoover Dam")
 tech_req       = "Electronics"
 bldg_req       = "None"
 graphic                = "b.hoover_dam"
 graphic_alt    = "-"
 terr_gate      = "Mountains"
 spec_gate      = "River"
-equiv_range    = "Player"
+equiv_range    = "Island"

 [building_js_bachs_cathedral]
 name           = _("J.S. Bach's Cathedral")
 tech_req       = "Religion"
 bldg_req       = "None"
 graphic                = "b.js_bachs_cathedral"
 graphic_alt    = "-"
 ;terr_gate     =
 ;spec_gate     =
-equiv_range    = "Player"
