Clear out HTTP server from Core

[hgn]

It was a dumb idea to integrate the web server directly. The web server functionality should be separated and the IPC can be done by simple REST calls. Heading over local topology information via REST. Whatever.

To remove the web server code on the other hand is not adequate. There are some nice visualization objects implemented. The best idea is to clone the repository into a temporary router-webserver where the core webserving functionality is executable. In a second step the webserver code should be removed from the DMPRD.
