Fixing Errors with useAddNotSet (for the most Servers)
Fixing error on /vip list if the list is empty
Change Command: /vip buy <Time> to /vip buy <Group> <Time> (Set a price for the Group in the config.yml, if Group is not in config.yml its not possible to buy the group with your economy plugin)
Fixing a Bug for longer VIP Time as you paid for. So if the Group changes, the Time will reset and not be added
Fixing EConomy - its not always disabled anymore
Fixing /vip import <Textfile>: I forgot to update this Command from v1.x to v2.x
