Added marmoset integration to seashell

TODO: need to add the UI code (currently, projects can be submitted from the js
console with socket.marmosetSubmit(seashellProjectName, marmosetProjectName)

Also haven't been able to test much since marmoset_submit isn't on ugster, but it calls the script correctly
Merge branch 'master' of https://github.com/cs136/seashell
