[FEATURE] Reproducible builds

[IzzySoft]

At IzzyOnDroid we support Reproducible Builds (see: Reproducible Builds, special client support and more at IzzyOnDroid). Trying for yours, I was able to successfully generate the APK for v0.7.1 using ./gradlew assembleRelease, but the resulting APKs were not identical, having differences in classes.dex:

(plus some more like those). Since v0.7.3, we cannot even build anymore due to this: Github's maven requires credentials, which our "anonymous builder" don't have. We could try again if those two libraries were included by other means (e.g. as git submodules) – though I'd expect the above issue to still be present then (and have no idea yet how to solve that).

We'd appreciate if you could help making your build reproducible. We've also prepared some hints on reproducible builds for that.

Looking forward to your reply!
