Web GUI update

Updated the Web GUI to use bootstrap and have a cleaner design (fully responsive). Removed the big logo at the top, since most people are interested in the published modules and not a header. Put a static header on top, and it will be easy to add login buttons when it gets to that point. 

Put pictures below, but running locally would probably be better.
