Merge branch 'sdunks' into Denis
minor change to app.py
cleaning up my branch
made vidoes that are added autoplay. playlist style seems to work already
got rid of the paths to the youtube videos from appearing on the screen; also applied a quick fix to the ugly formatting of the onscreen display of address
Merge pull request #10 from stuycs-ml7-projects/Denis

I merged it but this means we need to merge my stuff next to make sure the centering still works and stuff.
