added a input-field for setting 'fileHost'
Set this to avoid error-messages like 'proxy use not allowed / granted'
on accessing your Peer by its hostname.
fix for catchall handling in search
added new 'firstSeen' database table and necessary data structures which
hold a date for each URL to record when a url was first seen. This is
then used to overwrite the modification date for urls upon recrawl in
case that the first-seen date is before the latest document date. This
behaviour is necessary due to the common behaviour of content management
systems which attach always the current date to all documents. Using the
firstSeen database it is possible to approximate a real first document
creation date in case that the crawler starts frequently for the same
domain. As a result the search results ordered by date have a much
better quality and the usage of YaCy as search agent for latest news has
a better quality.
fix for wildcard patch in search queries
fix in key enumeration methods for cases where the enumeration is done
in reverse order.
