Made orbital arcologies ideal planet class(100% habitability)
Added planet bonus similar to the planet bonus of ecumenopolis

轨道理想城改为理想型星球类型（锁定100%宜居）
在轨道理想城上添加同星球理想城的加成

Lift restrictions in previous update
Fixed checks for whether the planet has upgraded capital buildings

将前一个更新中的限制取消
修复了检测星球是否有升级后的首都建筑代码

Fixed missing entity for city_habitat planet class.
Arcology decision on habitats now requires fully upgraded capital to improve compatibility with other mods adding new capital buildings.

修复了轨道理想城模型消失问题。
新增居住站理想城计划需要将首都建筑完全升级。

Added colony designations unique to city-habitat.
添加轨道理想城独有的行星特化。

为了不让普通行星特化出现在轨道理想城上，覆盖了的游戏本体代码如下：

is_special_colony_type = {
OR = {
has_modifier = penal_colony
has_modifier = resort_colony
has_modifier = slave_colony
"uses_district_set = city_habitat"
}
}

I've overwritten the above block to avoid having regular colony designations appear on city habitats.

mod现在通过修改planet_class来完成。大幅度提升兼容性。

Now uses planet_class to implement instead of planet_flag.

Updated for 3.3
更新至游戏3.3版本

修复了一个拥有特殊工业国策国家的工业区未能正确响应行星特化的bug
Fixed a bug where industrial district incorrectly respond to planet designation for countries with special industrial civics.

Updated so that industrial and habitation district can be converted to arcology districts.
现在居住区划以及工业区划在完成理想城后会被转化为理想城区划
