with proxy handler, what is currently
- use switched on in config
- access from a local IP / hostname
fix shutdown exception for crashprotection handler on interrupted connections.
- the implementation is inspired by Jetty's DefaultServlet
- handles static html content and YaCy servlets
- translates between standard servlet request/response and YaCy request/response specification
With the implementation of YaCy-servlets as servlet instead via a jetty handler it's closer to servlet standard and carries less jetty specific dependencies.
