sort order of components in simulator

[k-rieck]

before the calculation sort order of components to make sure that there are no useless calculations:
put componenents with no inputs first, then mixed inputs and at last components with no outputs
components = […]
no_inputs = []
mixed = []
no_outputs = []

NICHT! .sort()

for c in components:
if c.inputs_count == 0 && c.outputs_count > 0:
no_inputs.append©
elif c.inputs_count > 0 && c.outputs_count == 0:
no_outputs.append©
else
mixed.append©

alles wieder zusammen und weiterrechen
