some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

- 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

- in all cases that the parser is entered it is a whole set of possible parsers computed according to given mime type and file extension,
that means that all parsers are considered where the registered mime acceptance and extension acceptions matches.
that may cause that several parsers are tried for the same file which will cause a success in cases where there was only the mime type was used to choose the right parser and the mime type was given wrongly by the host httpd.

- added image size as part of parsed text in images
- avoid unnecessary error messages if parsing of documents failed but one succeeded

- image parser that implement the document parser interface return itself in the list of images of the document which should cause that the parsed images contribute to the image search

- fix for image parser
- temporary integration of images as document types in the crawler and indexer for testing of the image parser
