/**
 * Adds a new user to anopes internal userlist.
 *
 * If the SVID passed is 2, the user will not be marked registered or requested to ID.
 * This is an addition to accomodate IRCds where we cannot determine this based on the NICK 
 * or UID command. Some IRCd's keep +r on when changing nicks and do not use SVID (ex. InspIRCd 1.2).
 * Instead we get a METADATA command containing the accountname the user was last identified to.
 * Since this is received after the user is introduced to us we should not yet mark the user
 * as identified or ask him to identify. We will mark him as recognized for the time being and let
 * him keep his +r if he has it.
 * It is the responsibility of the protocol module to make sure that this is either invalidated,
 * or changed to identified. ~ Viper
