Lock Rotation when screen is manually rotated.

Additionally DisplayManager now accepts a source of display rotations. Those triggered by explicit user input (display settins, ctrl+shift+f3) will be stored as a part of display settings. Those triggered by rotation will not.

Upon exiting maximize mode the display will be returned to the last rotation explicitly set by a user.
