- added a new RSS reader interface. This is not finished but you can now load and look at RSS feeds. It will be used to index RSS feeds in a way that is appropriate for such kind of data.
- refactoring of Mediawiki and PHPBB3 loader interface names (just renamed) - removed two old not used RSS loader interfaces - fixed a bug in RSS parser library of cora - added a new RSS parser component to the set of yacy document parsers git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7053 6c8d7289-2bf4-0310-a012-ef5d649a1542pull/1/head
