[IDA/C2E] Change interfaces to use IDF/IPF values

[Samuel Jackson]

The are a number of parameters defined in the IDF/IPFs for the indirect instruments which could be used as default starting values at various points in the interface. Update the GUI so to use these values, but still fall back on the old default value for backwards compatibility.

Spoke with Spencer this morning and these are the only two areas that currently need data loaded from the IPF files.

To Tester

There are two things to test. First check that Elwin interface is loading the correct value for the log name. This should be initially blank. Selecting a file should retrieve the log name from the plotted workspaces instrument or default to "sample" if unavailable. Most of the instruments have this value set to "sample" anyway, but for testing purposes I would suggest changing the property in the of the IPF files (e.g. IRIS_Parameters.xml) and running a fresh reduction using the C2E interface, then loading this in Elwin.

The second thing to test is plotting a energy in the calibration tab of the C2E interface. The rebinning low and high values should be set to +/-10*resolution. The background start and end should also get set to -9*res and -8*res respectively. Otherwise they should default to the same values as before this ticket.
