Modding

• Added EntityPrototype::protected_from_tile_building, true by default. If set to false - entity won't block tile mining/building (with TilePrototype::check\_collision\_with\_entities enabled).
• Added LandMinePrototype::trigger_collision_mask.
• Added EntityWithOwnerPrototype.
• Added EntityWithOwnerPrototype::is_military_target and allow_run_time_change_of_is_military_target.
• SimpleEntityWithForce now inherits from SimpleEntityWithOwner.
• SpiderEnginePrototype::military_target is no longer used. If anything is provided it will make related SpiderVehiclePrototype to become a military target instead.

Scripting

• Added LuaEntityPrototype::trigger_collision_mask read.
• Added LuaEntity::is_military_target read. This deprecates LuaEntity::is_entity_with_force.
• Added LuaEntityPrototype::is_entity_with_owner, is_military_target and allow_run_time_change_of_is_military_target read.
• Added LuaEntity::get_spider_legs().
• Added LuaEntity::neighbours read for cliffs.
