versionCode not increased?

Just to let you know that v1.5.1 won't make it to IzzyOnDroid (or to devices having 1.5.0 installed) as it has the same `versionCode` (6) as v1.5.0 already used. Please always increase it with each release 😉 (PS: Better not replace the APK at the release, though, as some folks might already have picked it up – as most likely has one of our RB builders. Better make a new (maintenance) release. Thanks!)
