Version 3.1:

* Fixed issue with loans being taken at 0, and then eventually blacklisting shops
* Fixed auction issue where items floating look strange
* Fixed incorrect display for /trigger debt
* Created actual documentation
* Fixed sign hover item display to not flicker
* Fixed sign hover timer to only flicker on seconds changed (couldn't find way to make it smooth without re-writing a bunch of stuff, and it looks pretty good the way it is now)
* Fixed bug where you can set max uses to 0 (now can only be infinity or anything more than 1)
* Fixed default values for sign setup (can't have less than 1 quantity/price)
* Buying stuff no longer erases carpet, but it stores the blocks very far away.
* Player shops, cool.
* Added auction and bank to the teleports list
