• Removed rocket silo rocket prototype property "result_items" because it did nothing.
• Added draw_as_light and draw_as_glow property to sprite definitions. draw_as_shadow, draw_as_light and draw_as_glow are mutually exclusive and draw_as_shadow takes precedence.

Scripting

• Renamed the clean_cursor method to clear_cursor.
• Renamed on_put_item to on_pre_build, as it is much more precise name for that event. It fires when anything is used for building: item, blueprint, blueprint record or ghost cursor.
