Modding

• Added uses_stack to the thrown capsule item action.
• Removed the rail-category prototype type.
• resource_autoplace_settings has been made public (require('resource-autoplace').resource_autoplace_settings) and the API improved. It will automatically allocate a unique resource index for each patch_set_name. 'patch_set_name' and 'autoplace_control_name' can be independently specified. 'seed1' can be specified as a parameter. The global function 'get_next_resource_index' is obsolete and has been deleted.
• Equipment shapes can be defined as "manual" (a set of points).
• Added optional lamp prototype property "always_on".

Scripting

• Added "entity_to_ignore" to LuaSurface::request_path.
• Added target, orientation, and orientation_target to LuaRendering::draw_polygon().
• Added LuaGameScript::item_subgroup_prototypes, item_group_prototypes, fuel_category_prototypes, resource_category_prototypes, achievement_prototypes, module_category_prototypes, equipment_category_prototypes, trivial_smoke_prototypes, shortcut_prototypes, and recipe_category_prototypes read.
• Added LuaControl::character_mining_progress read.
• Added LuaEntity::can_shoot().
• Added LuaEntityPrototype::always_on read.
• Added LuaGuiElement type "line".
