Quota point system with configurable shop

[Deaththth]

Basically all runs led/security action points would be summed up in an balance.
This balance can then be used in a staff shop.
Admins can add and remove items from the shop as well as set prices through a configuration command.

This feature could not only motivate our top runners, but give every staff member an incentive to keep running as well as stay as staff in order to work towards a certain item and then purchase it.

For now only balance and command adds and reduces (automatically adds by quota)
