This version should solve now after a complete rework of the friend add/remove and clan join, kick, disband logic several of the recently reported problems eiter with Friends and/or clans not working properly at member-actions.
Secondly it should resolve the NTeleporation limitations of players trying to port to a fresh added friend or clan-member.
Added a "blockBuildNoIceBergs" option switch to the blocking part.
TRUE would disallow building on icebergs. "blockBuildIntoBlocked" must then also generally be active.
