Android 0.3.13

Android APK build of Reticulum Web Client 0.3.13.

Install: download the APK below, tap it on your phone, accept
the one-time "install from unknown sources" prompt. The app
registers as "Reticulum" on your launcher and requests Bluetooth
permission on first connect.

Same underlying code as the web app at
https://thatsfguy.github.io/reticulum-lora-webclient/ — if an
issue reproduces in the web version too, file it there.
