Adds a 5 second cooldown to warp transmitters after using return pad (#618)

<!-- Some improvement that requires no action on the part of add-on
creators i.e., improved star graphics -->
## Improvements
- Added a 5 second delay to warp transmitters after you come back
through the return pad. Means 360 degree alignment target actually works
when returning through it instead of sending you straight back.
(resolves #563)
