Rework calculation of min/max flow rates for simulation view colour scheme.

Browse source 
The max value was being calculated as the product of the max line width, max layer thickness
and max feedrate but it should be calculated as the maximum of the products of the width,
thickness and feedrate for each individual line. i.e. calculate the flow for each line
and use the min and max values of the flows.
