NullPointerException occurred when using and Identificator instance
which encountered and error in its constructor.
This error could be caused by a missing "langdetect" folder in the
current folder of the main process, or by simultaneous first calls to
the constructor, initializing concurrently the DetectorFactory.langlist.
Fixes the mantis 714 (http://mantis.tokeek.de/view.php?id=714)
Reduced this vocabulary memory usage :
- by using only one map term2entries instead of two maps having the
same key set
- by generating the location object links on the fly using the
GeoLocation data instead of storing many duplicates of string prefix

Using String instead of StringBuilder instances in GeonamesLocation
allows to reuse the same immutable objects in the Tagging class.

Could occur when a search request was performed just after peer startup,
and the Switchboard Thread "LibraryProvider.initialize" had completed,
thus requesting a ProbabilisticClassifier not completely initialized
(and having a null contexts property).
Reusing the same geonameid Integer instance between `id2loc` and
`name2ids` maps reduces (a little) memory footprint.

This error occurs on /ConfigSearchPage_p.html and on search results page
when Metadata links are enabled.
The fix was to remove unnecessary use of hs.htmlExpand() which is now
part of highslide-full.js library file, currently not distributed with
YaCy (only includes highslide.js). The Metadata links work correctly and
the initial dynamic expansion offered by htmlExpand() did not bring much
usability.
As reported by @reger24, image and favicon viewing was broken with
unauthenticated requests on peers configured to require authentication
even from localhost.
So I unified viewing rights check in a single new function on
ImageViewer class.
This makes YaCy easier to configure when running behind a reverse Proxy.
The check on status avoids trying to update the page with error text
content when the server returned a 404 or 500 error message for example.
to work directly with javax.servlet.http.Cookie (rename headerProps to
cookieStore as is only used for this).
(Re)implement set-cookie in DefaultServlet to make cookieAuthentication
work as designed.
When starting a crawl from a file containing thousands of links,
configuration setting "crawler.MaxActiveThreads" is effective to prevent
saturating the system with too many outgoing HTTP connections threads
launched by the crawler.
But robots.txt was not affected by this setting and was indefinitely
increasing the number of concurrently loading threads until most ot the
connections timed out.
To improve performance control, added a pool of threads for Robots.txt,
consistently used in its ensureExist() and massCrawlCheck() methods.
The Robots.txt threads pool max size can now be configured in the
/PerformanceQueus_p.html page, or with the new
"robots.txt.MaxActiveThreads" setting, initialized with the same default
value as the crawler.
It can take any Date field of the index and displays a list of year strings
in reverse order by the year (not the score/count).
To allow to define the index field to use, the fieldname (and title can be
appended to the navi's name "year" e.g. year:load_date_dt:LoadDate
It works also with dates_in_content_dts field (from the graphical date
navigator). Here the query parameter from: to: are used on selection as
Query modifier (for other dates currently no query parameter available, so
selection won't work to filter search results).
Not included in the UI Searchpage layout config so far (for experiment with
it manual change to conf needed).
handler.
UrlProxyServlet splits url in parts to pass it on as parameter and
HeaderFramework constructs a url from param parts. This is obsolete if
already created url is used (makes HeaderFramework.getRequestURL obsolete
