Added a zim parser to the surrogate import option.

Browse Source 
You can now import zim files into YaCy by simply moving them
to the DATA/SURROGATE/IN folder. They will be fetched and after
parsing moved to DATA/SURROGATE/OUT.
There are exceptions where the parser is not able to identify the
original URL of the documents in the zim file. In that case the file
is simply ignored.
This commit also carries an important fix to the pdf parser and an
increase of the maximum parsing speed to 60000 PPM which should make it
possible to index up to 1000 files in one second.

<p>
This is an experimental setting which makes it possible to split PDF documents into individual index entries.
Every page will become a single index hit and the url is artifically extended with a post/get attribute value containing
the page number as value. When such an url is displayed within a search result, then the post/get attribute is transformed into an anchor hash link.
This makes it possible to view the individual page directly in the pdf.js viewer built-in into firefox,
for reference see https://github.com/mozilla/pdf.js/wiki/Viewer-options
