Score changes

Important update to the score system

DextranShape, Shape, ShapeBack, ShapeFront

have been updated so that they can run in decay or normal mode and use the derivative or not use the derivative, Their default is to do what they did before but an additional option can be added to configure each of them. This means that so many more scores don't need to be created so Shape can do everything ShapeDecay could do and also cover other cases

To configure the code in the features section for each score set

"derivative": 1 or 0
"decay": 1 or 0

Many of the existing scores are just minor variations on other scores and this causes 4 version to exist for each type of score. Part of the reason for creating this is that sometimes experimental data has glitches in it and while the main curve is smooth enough the derivative (even with smoothing) is quite bad and it makes sense to just turn off usage of the derivative but not create a new score just to do that.
