Android M crash fix

• Fixed crash on Android Marshmallow when the Fragment is recreated

Support for Android 8

• Fixed issues with Android Oreo (IllegalStateException)

Use delegates instead of inheritance

• Moved the plugin code to utilize delegates instead of having to override the callback methods
• Added sample script
• Big thanks to @Briksins for his contribution

Manifest overriding no longer needed

• There's no more need to override the main manifest - the plugin's manifest contains the necessary SkipPermissionsDialog metadata flag
