we can create links (hard links, symbolic links) now

added winix functions: ln winix function 'default' can be used without redirecting now added new tickets types: TypeProgress, TypeString, TypeMultistring, TypeImages, TypeFiles now tickets are combined with files added winix functions: showtickets fixed mountpoints: when the default root mount was created its parameter table was empty and it caused accessing to a non-existing objects fixed logger: modifiers (log1, log2, log3) were incorrectly treated added modifier: log4 (debug info) now we are moving threads to a new plugin 'thread' created directory: plugins/thread (not finished yet) git-svn-id: svn://ttmath.org/publicrep/winix/trunk@704 e52654a7-88a9-db11-a3e9-0013d4bc506e
