Feature/start videowebserver

Server, when it starts, starts one video webserver per robot. It is also able to kill the webservers when it stops.
Where do I even start?

We are passing to /bin/sh (without even knowing if /bin/sh is present in the system (a call to system(NULL) suffices)) a __huge__ string, using relative paths, escapes and launching.. A MAKE?
Ok, 'make start' will actually launch the python's web server but.. WHAT THE HECK.

In this line, we have killed K&R.
