bug fix (attribute selection order)

when the dialog was re-opened the order numbers were not set correctly.
The hcscore-1.1.jar was not really changed

I first thought I need to change something in the Well class in the model package, compiled it for testing but later reverted it. Even though the compiled code might look differently to the VCS, the code behind is still the same.
part of the previous bug fix (tow commits ago)

The selectedAttributes is not inverted anymore, instead it is iterated through from the end to the start.
Since the variable with the inverted list was not properly separated from the selectedAttributes, the inverting process was affecting both variables which lead to chaotic behaviour.

refactored type in a field name
"overlay" field name refactoring in the HeatMapModel

... to "currentOverlay" so it is more explicit (looking forward of having to add yet another field concerning overlays...)
Maintaining the order of readouts and factos as given by the input table (issue #8)

This factor and readout lists are now passed to the HeatMapModel as additional fields. I am not very happy with this solutions, in my opinion LinkedHashMaps to store the well statistics and annotations would have been better, to keep the order as derivable parameter. But I did not want to remodel the Well class (I could not find a neat way of running old and new in parallel without it being confusing).  This way there is another possible source of errors.
I also had to adapt the Tests to accomodate the additional functionality performed by the HeatMapViewerNodeModel.
Fixed the "order" column width in the PlateAttributeDialog

this was an old TODO... now the oder column is slimmer, using just the space of a couple of digits, instead of half of the panel.
Adding group label sorting for the overlay legend (issue #11)

...while I was at it I also added some comments for easier code reading.
