Hauser v0.50.0

• Room: every device on the picture can be resized like a lamp. A shape button switches between ellipse and rectangle, whose four corners can be adjusted individually like window corners; the button moves to the left near the image edge. Web and iOS share the shape, and the tappable area follows it.

• Room: the hint about devices without a position no longer floats over the room editor; it stays in the view settings.
