- changed yacy logo - removed crawlOrder protocol (unused) - removed file index in kelondroFlex (will not work, it takes too long to maintain) - fixed remoted crawl for clusters (now denies remote crawls from peers outside cluster) - 0.562 git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4317 6c8d7289-2bf4-0310-a012-ef5d649a1542pull/1/head
