We've decided to give visitors their level referring to their amount of XP.

There's no mandatory XP requirements for clan members. They gain higher levels by different qualities
(of course XP is one quality).

Visitor | LVL 0
This level is free for all (default level).

New User | LVL 1
They have to get 1k (1000XP) to gain this level.

Regular User | LVL 2
They have to get 2k (2000XP) to gain this level.
Now recruiters have seen this player being active for a while and can possibly recruit.

Advanced User | LVL 3
They have to get 5k (5000XP) to gain this level. Visitors can't get any higher from this.
It's the highest level for visitors to acquire.

LVL 4 is for allied clan members.
Ex-members get LVL 3!
