*) adding support of proxy access logging (much similar to squids

access.log) file
*) splitting doGet function in separate functions for fulfilling
   requests from cache and from web to make error handling easier
*) using connection property and httpHeader constants instead of
   hardcoded strings whenever possible
*) sending back a proxy error message as body of every respond
   containing a http error code
*) correcting problems of messages received from other proxies
   containing 204, 304 status codes.
*) using chunked transfer encoding if the server has not set the
   content length (e.g. because of gzip content encoding) but 
   the client has established a persistent connection to yacy.
   This is only possible for http/1.1 clients. For http/1.0 clients
   the connection will simply be closed on the end of the message.   
*) removing unneeded functions (e.g. respondError) because of newly
   introduced functions of httpd.java
*) removing hop by hop headers (according to rfc)
