Use FileProvider for all Android versions, including Android 5 and earlier

[imgx64]

Looking at the code, it seems that FileProvider is only used on Android API >= 23 (Marshmallow). This prevents opening files in private app directories (such as /data/data/app-id/files/*) in other apps on Android 5 and earlier.

I modified the plugin to always use FileProvider and it worked correctly on Android 4.1 (The earliest version supported by Cordova). And as a bonus, android.permission.WRITE_EXTERNAL_STORAGE is no longer required.

Is there a reason it's this way? Can it be changed?

Can you submit a PR for that? I'd like to test it.

PR in #176
