Attempting fixes for some hoist bugs. (#3027)

Hoists now release hoistees if they wriggle out somehow. Shouldn't happen anyway, but consistency_check should handle any odd shenanigans.
Silicons should be able to be hoisted. Buckling wasn't anchoring them, for some strange reason.
Fixed a bad message, where [user] was used instead of [usr].
You can't directly unbuckle people from hoist hooks.
