	* transporterdialog.cpp (TransporterDialog): Use wn to discern

	which cell a wallitem belongs to.

	* wallitem.cpp (WallItem): Add a comment explaining how

	wallnumber(wn) can be used to tell which cell a wallitem belongs

	to.

	* VirtualLeaf-install-windows.nsi: Remove previous change that added icon directory.

	* canvas.cpp: Instead of using a separate icon directory, compile

	leaficon_small.xpm directly into canvas.cpp.

	* VirtualLeaf-install-windows.nsi: Add new icons directory

	* canvas.cpp (about): Added virtual leaf logo to About message box.

2011-01-12    <guravage@petitdru.sen.cwi.nl>

	* transporterdialog.cpp (TransporterDialog): Add a proper title to

	the dialog, and place the cell and wall pairs in a seperate labe.

2011-01-10    <guravage@petitdru.sen.cwi.nl>

	* transporterdialog.cpp (TransporterDialog): Start numbering Transporter fields at zero.

	Resolves issue #1: http://code.google.com/p/virtualleaf/issues/detail?id=1.

	* wallitem.cpp (OnClick): Change dialog modality to Qt::WindowModal.

	Resolves issue #2: http://code.google.com/p/virtualleaf/issues/detail?id=2.

	* canvas.cpp (about): Add link to Plant Physiology paper.

	Resolves issue #3: http://code.google.com/p/virtualleaf/issues/detail?id=3.
