Beta 4: Brush size change with mouse wheel broken in free camera

The Brush Size change through the mouse wheel has been broken in all T3D Beta, when the camera is in free flight mode.
While beeing attached to the player, it works without problems.

This is caused by

EditorMap.bind( mouse, zaxis, mouseWheelScroll );

in toolsWorldEditorscriptsEditor.bind.ed.cs

As a temporal solution just comment it out if you want to be able to paint and modify your terrain fast again.
