Feature/fast resource workflow

Adding some interface modifications that allow the user to:

1) User gets forwarded to their user page after adding a resource (controller.js mode)
2) The previous connection is set as the StartResource in the triplet (app.js and controller.js)
3) The triplets on user page are sorted according to most recent ones (controller.js)

Possible issues: let's first merge it into p2p-science-alliance branch to see if there are any speed issues with showing the User's page each time a user adds a resource. It's a heavy request, so I suggest we test it on that instance by adding several collaborations ourselves, and judging the speed. If there's a problem, we can always roll back to the commit before this merge.
