Clean up

[ataffe]

This is a clean-up of the whole project including changing to using relative paths. This is in preparation for #24

I need to test that everything starts up ok after the clean-up.

Still seeing some paths to Desktop and I can't seem to get this guy up and running.

I did some googling and throwing this at the beginning should help us clear up any relative path issues, this way it doesn't matter if they run it directly or using the full path.
os.chdir(os.path.dirname(os.path.abspath(file)))

Also, for those less technical than us, thinking we should post the port number up when it starts up so they will see which port it's on. And I'll also add some info on packages, cause I setup a VENV for this so I have a full list of all the packages I needed to get them running.

I forgot about log directory, is there a way in python to create that dir, cause needed to create it manually.
