If you embed a snap project we should replace the URL with a snap! embed page

[cycomachead]

Turn a url like this:
https://snap.berkeley.edu/project?username=avi_shor&projectname=stamps
Into:
https://snap.berkeley.edu/embed?projectname=stamps&username=avi_shor&showTitle=true&showAuthor=true&editButton=true&pauseButton=true

Format of a "correct" URL
https://snap.berkeley.edu/embed?projectname={PROJECT_NAME}&username={USERNAME}&showTitle=true&showAuthor=true&editButton=true&pauseButton=true

Conditions: snap.berkeley.edu has query username and projectname --> "fixed" url
