a36fda991e hack to increase speed of url hash computation

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

746e3c3b06 Replaced a widely-used Property Object in the httpd with HashMap<String, Object> which is not synchronized like Properties
A synchronization is not needed here and applies an overhead to the httpd process which is now removed.

cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.

b6fb239e74 redesign of parser interface:
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.

- simultanous import from several servers (even > 2000)
- check buttons on OAI-PMH server list to select multiple servers for import start
- it is possible to select all servers at once for import
- imported XML data is gzipped after import from surrogate reader

1a8a134e0c continuing String-hash - to - byte[]-hash redesign that was started in SVN 6775 and continued in SVN 6790
The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)
