Ability to clear queued purchases from the shop

[svaller]

When we wipe a server we clear all player currency and all player teleports. These features work great. We however are unable to clear any currently queued purchases that haven't been claimed yet. This causes problems when some players will spend their money prior to the wipe to queue up items so they can claim them after the wipe.

We usually let our players know when we are going to wipe as a courtesy and to keep them coming back. The small handful that stage items for after the wipe frustrate me and I can't find a way to circumvent it.

Please add the ability to clear all unclaimed purchases similar to how we can now clear all currency and all teleports.

Notes for implementation:

I suggest we add a button to the economy settings that clears all queued shop items. There should be a confirmation message ("Are you sure?"). It then calls an API that clears all the PlayerClaimItems from the database for that server
