Port-a-med minor (but actually major) fix

[Lavastage]

Make it work like an actual sleeper with a console so you can inject rejuvinating agents into people using the remote.

Change the remote function so that it would just follow you instead of teleport (we got the porta-sci now anyways) and this would be perfect.

Though, make it have a battery life or something so it would have to go back to medbay to recharge. in fact, just have it be a function on the remote to send the dork back to medbay via hovering instead of teleportation (using mulebot code.) Cue antagonists intercepting the porta med for shenanigans.
