yacy_search_server/htroot/yacy/message.java
orbiter 99bf0b8e41 refactoring of plasmaWordIndex:
divided that class into three parts:
- the peers object is now hosted by the plasmaSwitchboard
- the crawler elements are now in a new class, crawler.CrawlerSwitchboard
- the index elements are core of the new segment data structure, which is a bundle of different indexes for the full text and (in the future) navigation indexes and the metadata store. The new class is now in kelondro.text.Segment

The refactoring is inspired by the roadmap to create index segments, the option to host different indexes on one peer.
