- added more properties to solr index - refactoring - more constants in switchboard - fix for some NPEs - recognition of more images - removed synchronization in HandleMap (obviously not necessary?) - added a nolocal configuration to remove excessive dns lookup (works only on allip - default off). Indexes produced with this setting are all flagged with 'local' and are (on purpose) not usable for freeworld because they will be rejected as beeing local. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7672 6c8d7289-2bf4-0310-a012-ef5d649a1542
