Resolve "Group Page: Popup Annotations should not go out of the viewport."

Closes #1548 (closed)

It now works with the q-tooltip component. It now gets scrollable and auto aligns on different sides if the viewport is too small. (By default it now aligns at the top)

@christian.hansen @isabela.dimarco @milan.gress I also added a allUsers array to the ContinousGroupPull.js it combines the creator and the members in one array. In the allUsers array they now also have a .isActive boolean which is true if the user made a contribution since the last pull.

And there is a new Array currentlyContributingUsers which holds the id's of the users which made a contribution since the last pull.
