the kelondro database needs specific information about the order of base64-encoded keys. Since no other package depends on base64 (only the httpd uses base64 for encryption, but does not need to encode these strings) it is good to move base64 encoding to the new ordering classes in kelondro. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@1284 6c8d7289-2bf4-0310-a012-ef5d649a1542
