added new interactive search feature:

Browse Source 
- during the user types search queries, the local database is searched
- results are presented interactively

This was implemented using a new JSON result format for search results in YaCy
- added JSON as file format for servlets
- refactoring of current search servlets (xml and html)
- added JSON output format for search results
- added AJAX-based search page, that uses the yacysearch.json selrvlet to print results as a query is typed
