implemented a hint from dulcedo "use site: - operator as crawl start point".
YaCy already was able to search using a site-constraint. This function is now extended with a instant crawling feature.
When you now use the site-operator, then the landing page of the site iand every page that is linked from this page are loaded, indexed and selected for the search result within that search request. When the remote server responds quickly enough, then this process can result in search results during the normal search result preparation .. just in some seconds.

a cache access shall not made directly to the cache any more, all loading attempts shall use the LoaderDispatcher.
To control the usage of the cache, a enum instance from CrawlProfile.CacheStrategy shall be used.
Some direct loading methods without the usage of a cache strategy have been removed. This affects also the verify-option
of the yacysearch servlet. If there is a 'verify=false' now after this commit this does not necessarily mean that no snippets
are generated. Instead, all snippets that can be retrieved using the cache only are presented. This still means that the search hit was not verified because the snippet was generated using the cache. If a cache-based generation of snippets is not possible, then the verify=false causes that the link is not rejected.

- removed concurrency overhead for small number of index normalizations as it happens during remote search
- removed 'load only parseable' constraint for snippet fetch because some resources may not have any url file extension and these had therefore not been parseable and searcheable since they may become parseable after loading when their mime type is known
- this partly fixes some problems with http://forum.yacy-websuche.de/viewtopic.php?p=20300#p20300 but more changes are necessary to get all expected search results

- a new news db will be created (news1024.db), the old one (news.db) can be deleted
- peers with too large news payload are not ignored any more (they may have been invisible because they had a too large news payload!)

- now xms is lower than xmx (lets try what happens)
- removed default path for intranet crawl starts to avoid confusion as seen on linuxtag
- added time-out to upnp request (i have a new router which may need that)

- crawl lists for each domain now uses a HandleSet which should use less memory than LinkedLists
- but: fill more entries into the domain lists (all available entries)
- fixes to selection criteria (best domain selection)

- it is now possible to crawl the local file system with an intranet peer
- redesign of URL handling
- refactoring: created LGPLed package cora: 'content retrieval api' which may be used externally by other applications without yacy core elements because it has no dependencies to other parts of yacy

- added number of online peers at the last day and the last week
- changed design of statistic table
- network picture now shows exactly those peers that are counted in the statistic overview for one day

- order locations by (primary) population and (secondary) longitude (reverse ordering, both)
- added population from GeoNames, OpenGeoDB does not have that information
- changed default viewpoint of map to (30,15); shows more land and europe in the center

- added ViewFile in location pop-up

- used that to display two layers on map: cities and search result locations
- added many marker grafics for the display of the markers on the map
- some refactoring of the yacy news code plus bugfixes for latest move from Tree to Table data structure

- more abstraction using the libraries

- more String -> byte[] migration
- more logging for cache store/hit
