join fix - disappered in commit + Switch traffic joins, because its faster - Tested in a productive system (MySQL 5.1) as query few tausend domains 1-3 sec for Webtraffic sort, faster SQL = faster and MySQL 5.5 is much faster with joins (standard is not sorted with slow traffic querys) -> slowest part is coping the tables into temp -> more tweeks on cache... -> faster by heavy use

fixed sorting from traffic, changed sessionvaribale because listDef[name] is by mail and web the same but different columes. Additional added table aliases in 'order by' by joins. Added table by log because server_id^C join server_id = sql error

Sort and limit in ispconfig all templates... additional info howtoforge - http://www.howtoforge.com/forums/showthread.php?p=274790
