Refactoring camera and panel names to make sense

:camera: :+1: 

Having camera and panel names like "Left Camera" doesn't make a lot of sense because we have to change it to "Right Camera" when we flip the camera to the opposite side. It also makes the menu item Window>Show Top seem weird. 

If we give them axis name, then we have panel names like "X-Axis Camera (Right)" that becomes "X-Axis Camera (Left)" and the Widow menu items becomes "Toggle X-Axis Camera" and stays that way.
