Highlights:

scypt recipe has been updated.
--orientation option controls the allowed orientations (portrait, landscape, portrait-reverse, landscape-reverse). The allowed orientations list is then set to KIVY_ORIENTATION environment variable, which is used during window setup time to populate the SDL_HINT_ORIENTATIONS value, as we're doing for other platforms.
--manifest-orientation option has been added to keep the android:screenOrientation personalisation functionality, even if Android will be likely deprecate this attribute in future.
If --manifest-orientation is not set, and only (one of multiple) --orientation options are passed, the value for android:screenOrientationis guessed and synthesized from the --orientation option. Sinceandroid:screenOrientationaccepts only 1 value, if multiple--orientationare given,android:screenOrientation` will be set to unspecified.
Introduced support for permission properties (maxSdkVersion and usesPermissionFlags)
