UUID Support, Adminshop Ignore, Message Config

Enables the support of UUIDs (it does not have a converter yet, I may code a convert command later on. It creates a new table csnUUID and does not override the existing one!)

Adds a config option where you can toggle if the adminshop should be ignored and not saved in the database if users buy from or sell to it.

Adds the ability to define all messages in the config.
