Expose ability to set/get EFixed to python

[Stuart Campbell]

It would be useful to be able to get/set the EFixed value from Python. We can already set the Efixed (Ei) for direct geometry as this is just a log. We need a way of setting it for indirect geometry instruments that store the value in the ParameterMap.

To Test:

The easiest way is to load a data file from an indirect instrument (e.g. BSS_11841_event.nxs in the AutoTestData directory). Then get the EFixed for a detector, change it, then get it again to make sure it was changed. So something like:

w1=Load("BSS_11841_event.nxs")
print w1.getEFixed(19)
w1.setEFixed(19, 6.666)
print w1.getEFixed(19)

Note: there is nothing special about the detector 19 or 6.666 meV values that are used above.

I've tested that the change is picked up by ConvertToMD, in the preprocessed detectors workspace
