principles:
- provide an easy tutorial-like "what should I do first" menu
- provide all elements which are subject to most first questions to YaCy
exibition people on top level: Resource limitation, Parser and Ranking
settings
I apologize to everyone who are used to the old style and need to find
the menu items (again) after this change. I hope that this will make the
interface more usable for new users who see a web indexer/crawler the
first time.
