Code for parsing the request itself is good
Saving the URIs that controls the video & the audio.
This was done in a really half-assed manner and should nvr be used
seriously.

As a general remark, this code is quite crap. I only wrote it for this
bloody workshop I need to complete to get my degree.
I seriously hope one day i'll write good code even when its meant to run
once and just get me a decent grade... :'(
Prepared a couple of tests for the setup message
Included the setup test in the happy flow test
* Generating an appropriate response for a SETUP message :)
* bug with RTSP version considered a part of the URI fixed
* bug that considered 'transport' a MUST in each request fixed
Apparently VLC demands to have a session field for the setup :)
Merge branch 'handle_setup_msg'
