- changed build script to use java 1.5 compiler - first stept to resolve missing generics definition (about 400 from over 4100 'missing'-warnings) - added key-iterator to kelondro databases (for rapid from-memory enumerations, will be used for domain name collection, not used yet) please set your development environment to use java 1.5! git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@4292 6c8d7289-2bf4-0310-a012-ef5d649a1542
