Spielekiste for Android

The newest build of the Spielekiste for Android, from commit dc818fe (build 57). This release is replaced with every change to main.

Installing: download spielekiste.apk below and open it on the phone; Android asks once to allow installing apps from that source. A newer APK installs over an older one and keeps the app's settings, and the app can look for a newer build and install it itself.

This is a debug build, signed with the project's debug key: for testing and playing with friends, not for the Play Store.
