Change back button behavior

[diskmanti]

At the moment when the back button on android is pushed the app closes down entirely.

It would be helpful to change this behavior to something else. For an example, when you want to answer a question about a mission but you realize you clicked the wrong mission, pushing back would close down the complete mission window and show the entire map again.

Hi dikmanti, Thanks for the issue.

Kort development has stalled end of 2017 and there are currently not maintainer nor dev resources available on this project. Around October 2018 there will be some shiny activities in order to resurrect this nice game experience.

Pull requests are still welcome in the meantime :-).
