[Enhancement] Configurable delay & cooldown on teleport commands

[Absentee23]

This is a feature I've missed and have had to add a whole other plugin to all my survival servers just to combat this exploit: A player can instantly tp away from danger with any teleport commands.

Please add a configurable delay & cooldown timer for teleporting, which would be cancelled by damage and movement. With it's own message to inform players why they didn't instantly teleport. Something like "Hold still and wait {time} seconds" or even just "Hold still to be teleported."

Note: this should NOT affect portals, those should always be instant.

Thanks!

:edit: wow, sorry. I forgot I had requested this before in a reply to another feature request. Deleted that and left this here, feel free to close if you don't plan on adding it.
