Git commit 3d876f8d6dbe138378026d9f3ee7a07ef0b4135a by Matthias Kretz.
Committed on 01/02/2012 at 23:51.
Pushed by mkretz into branch 'master'.

allow setting a due date via mousewheel

Setting the due date with the mouse is easier now (for me). Double-click
the cell and use the mousewheel to select the date. The mousewheel thus
does the same as the up/down cursor keys.
