Change the default setting for newly created map elements to send right clicks to mouse procs.

Would be as simple as adding in the right-click = true line to the dmf code when a new map element is created in the dmf editor.

By only changing the way that new map elements are created, this would not affect existing map elements in current games. (backwards compatability)

The reason that I'm requesting this is that the current behaviour makes the current mouse control inconsistent with the default engine settings, and therefore more approachable to newer users to the engine.
