Exported provider permissions - readPermission/writePermission overlooked

When checking exported providers in the Application Manifest, QARK checks for the `android:permission` flag. If it can't find it, it assumes the provider is not protected by a permission. However, you can use `android:readPermission` and `android:writePermission` to set the individual read/write permissions. QARK should check the presence of these attributes if no android:permission is found.

Start at QARK's Application Manifest provider-permission check and compare its handling of android:permission with the Android provider-element documentation linked in the issue. Trace the exported-provider check and verify that readPermission and writePermission are considered when the general permission is absent; done means those protected providers are no longer reported as unprotected.
