Adjust Sequential fitting dialog to enable fitting across workspaces without log values

[Nick Draper]

Requested by Jon Taylor:

Jon wants to be able to fit multiple workspaces, but has no log value of particular interest, so would just like the data outputted with the workspace name. One option to do this would be to add a workspace option to the log drop down list. Another would be to identify if we have more than one WS in the input when no log is selected and then use ws_index as the column label.

In addition he would like the quality score (ch12) in the results table as well.

Added option to PlotPeakByLogValue to output ws names instead of log values, modified SequentialFitDialog to us it. re #3511

In [13878]:

PlotPeakByLogValue doesn't use file finder for this test to work. Disabled. re #3511

Both aspects of the ticket tested and work.
