Invitation codes #31

Invitation codes could be a good alternative to registration captchas.

Every user is allowed to create an invitation code/link, like https://example.com/invitation/ABCDEF. Whenever a new user wants to register, he has to use a registration code or an invitation link in order to register. In the database, the new user is linked to the user who invited him. This creates an 'invitation tree':

A
|- B
|  |- C
|  |- D

|- E

I implemented DISABLE_USER_REGISTRATION a while ago. This serves a similar purpose: to prevent spammers to register for an account long after the competition has started.
