KeeperFX for Android 1.52 (unofficial, compatibility pointer)

Unofficial community build, not produced or supported by the
KeeperFX team.

Always the same build as the newest android-v* release, kept
so that app versions up to 1.4.0.5289 can still find their update. It is
flagged as a prerelease so it never shadows the real one.

See android-v1.52 for the changelog.
