Marble: Add Credits and sort the Tour/EditMaps/FileView tabs
completed by: Daniel Pastushchak
mentors: Dennis Nienhüser, Torsten Rahn, Sanjiban Bairagya, shentey
Part 1:
Currently Marble's about dialog only pays credits to the Google GCI 2011 to 2012 students.
However the Marble project also had students in the years 2013-2014. Please research the GCI student names, e-mail address and the topic of their projects. Please add it to the about config dialog in a way that fits the previous entries (same wording, same formatting and in the correct order). For this year add the students who have contributed so far.
Part 2:
The Tour, Edit Map and FileView Panels are currently not pre-layouted.
This task is also about aligning Tour, Edit Map and FileView as a tab group like done for Search, Routing, Location (or MapView and Legend). This tab group should appear at the bottom in a "third tab group" (if all panels are enabled which is not the case by default for all of them).
