Add support for bird's eye camera view

Browse Source 
A new hotkey "hotkey.camera.togglebirdseyeview" allows to switch
between regular view and bird's eye (top-down) view.

When bird's eye view gets toggled on, the camera moves above the scene;
When bird's eye view gets toggled off, the camera moves back to the
default vertical rotation angle;
When bird's eye view is on, vertical rotation is disallowed.
