Auto-rotation skins on Free42 v3.0.7

[Thomas Okken]

Ah, right... the trouble with storage access started with Android 11, but there was a transitional option you could use in the app manifest, requestLegacyExternalStorage=true. But that only works for apps targeting api level 29 or less, so now that I'm forced to target 30 or higher, the work-around no longer works, and this issue needs to be dealt with.

I assume it is still possible to store skins under /data/data/<package_name>/files, since that's where the state files are as well?
