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).
