Support for landscape mode in 2.10.0.324

[dreadful-brain]

First thanks for making rmview work in 2.10.0.324. While working great in portrait, there is still an issue in landscape mode.
If you present a landscape file, and rotating rmview e.g. clock wise, rmview switches back to portrait mode as soon as you write something on rM.

Yes that's part of the orientation-autodetection mechanism.
This should only happen if you set "orientation": "auto".
What happens is that at every new frame, the autodetection tries to locate the UI buttons to determine if it's in landscape or portrait and adjust rotation accordingly.
The "orientation": "auto_on_load" setting restricts the autodetection to only the first frame, "orientation": "portrait" and "orientation": "landscape" disable the autodetection mechanism.

Could consider adding a menu entry to enable/disable autodetection.

I was surprised by this behavior as well. It seems like it would be better to "remember" if the user rotated the display clockwise until the next time they change it manually?

btw, autodetect seems to work reasonably well when the menu is opened, but not when it's closed, even though that little circle stays there and ought to be enough to guess orientation?

This was fixed in 166d6fc
Now manually rotating disables auto-rotation.
