- Improvement to web-shuttle: Don't update docking controller until jump() is completed.
- It is now consistent with autodock behavior (for better or worse)
- Add shuttle process_state to enable processing of web shuttle autopilot.
- Convert Arrivals shuttles to be a subtype of /datum/shuttle/autodock/ferry
- Default shuttle landmarks flags to SLANDMARK_FLAG_AUTOSET
- Made this safe and backwards compatible by having SLANDMARK_FLAG_AUTOSET not overwrite already specified base_turf or base_area
