* Pulling: Migrate critical pull state from PullController to SharedPullableComponent, fixing two bugs in the process
Bug 1: PullController can be just summoned for no reason when the verb is queried
Bug 2: PullController keeps it's own independent pull state which can (and will) go out of sync (See https://github.com/space-wizards/space-station-14/issues/2619 )
* Pulling: Fix issues with previous commit (or possibly in general?) causing transferring a pull to cause alerts to go wrong
The primary problem is that there is one "pulling slot" for a puller, so SharedPullableComponent needs to stop the existing pull.
* Pulling: Remove debug logs (whoops)
