Event Overview/Admin Overview: Enable "Open in Tab" on buttons

[mariobehling]

Currently the buttons to view, edit or delete an event on the overview pages of organizers or admins only permit to do the action. It is not possible to open the actual links in a tab. Please change this behavior as it would make things much easier for organizers/admins.
