version 80:
- Major rewrite for compatibility with Android 8/9 (Oreo & Pie). No longer
  works on android 3.0 and older -- please use an old APK (available at
  dcw.phauna.org) if you need that.
- Widget is now 2x1 instead of 1x1. It was unavoidable because wide margins
  are forced in the newer version of Android.
