yacy_search_server/htroot/IndexCreate_p.java
orbiter 61798f0ae6 added option to distinguish between text crawl and media crawl 
- for each crawl start, there is now a flag for text and media
- the localCrawl flag is superfluous
- added new crawl profiles
- if an image search is done, only media links are crawled for the snippets
