theli 02d9af1a70 *) Restructuring and extending of Remote Proxy Support
- remote proxy configuration can now be "really" changed on the fly and takes effect immediately
   - adding possibility to disable remote proxy usage for yacy->yacy communication
   - adding possibility to disable remote proxy usage for ssl
   - restructuring proxy configuration so that it is stored in a single place now

*) Adding possibility to import a foreign word DB (or even more of them in parallel) 
   at runtime into the peers DB
   - this can be done by calling IndexImport_p.html 
   - ATTENTION: please not that at the moment this thread must be aborted via gui
     before a normal server shutdown is done. 
   - TODO: integrating IndexImport Thread into normal server shutdown
   - TODO: Adding posibility to import crawl-queues, etc. from foreign peers
   - TODO: removing old import function from yacy.java and calling the new routines instead
