[Feature Request] UUID's instead of usernames

[MyTimeIsMoney]

Hello mastercake10,

can you find a way to use UUID's instead of the usernames (in storage)?

The problem is, if a user is rename the minecraft account all the money get lost, because the plugin is searching the bank accounts with the username.

It would be very helpful, because we have too many people every day with changed usernames and then we need to transfer every single bank account...
