Eraser button (in Area Editor, for selecting eraser brush)

Right now, selecting the "t_blank" tile is used for erasing. In a long list of tiles it can get cumbersome to find it again quickly.
How about adding an "Eraser" button that switches selected tile automatically to "t_blank". This button could be placed left hand side, directly above the "Selected Tile" box (and beneath "Fill map with selected tile").
