Redesign of the App

[Th3Ph4nt0m]

This is closing #9.

Changes

• The changelog is now displayed as a pop-up (previously as a full screen activity)
• All buttons now have a round design
• The Info Pop-up for the teacher initials has been removed
• The staff pop over now has a (small) distance from the edge
• A link to the settings has been added to the Alert Dialogs
• The settings now consist of multiple tabs (fragments)

  Developer comment

  The app has been given a more modern look. In addition, the settings have been divided into different sections to make it easier / nicer to integrate later functions.

Even after local deletion and a new clone, I cannot reproduce the errors mentioned. The branch has no conflicts with the develop branch (see Github), and the class you mentioned was not affected in this branch. The app can be started in debug mode both in the emulator and on a physical device.
