Saving fitting parameters using SaveParameterFile

[Anders Markvardsen]

To reproduce:

1. Load AutoTestData\UsageData\HRP39180.RAW

2. Run SaveParameterFile for this created workspace in 1

The output is e.g. for fitting parameter S:

		<parameter name="S">

			<value val="0 , BackToBackExponential , S ,  ,  ,  ,  , sqrt(188.149*centre^4+6520.945*centre^2) , dSpacing , TOF , linear ; TOF ; TOF"/>

		</parameter>

However it should be:

  <parameter name="BackToBackExponential:S" type="fitting">
    <formula eq="sqrt(7.429*centre^4+132.188*centre^2)" unit="dSpacing" result-unit="TOF" />
  </parameter>

Added block to handle fitting parameters in SaveParameterFile. Added unit test for fitting parameters.

For testing (as specified in the ticket description):

• Load AutoTestData\UsageData\HRP39180.RAW
• Execute SaveParameterFile algorithm
• Check the output file is as expected for parameter S and for the other parameters
• Additionally, check that output stays the same for non-fitting parameters, you may want to try different datasets, for instance I tried AutoTestData/ARCS_2963.nxs, AutoTestData/HET15869.raw, AutoTestData/MUSR00022725.nxs.
