TITANIC: Remove const prefix from passed messages

Turns out that some of the messages have properties that the objects
that handle them can set. For example, the CMouseDragStartMsg has a
_dragItem property that an item that allows dragging will explicitly
set, allowing the input handler to keep track of what was dragged.
