Results tree default naming needs more information

[ihumphrey]

Currently, the value shown for a 1-Time correlation is 1-Time Correlation. This should at least show the scanid tacked on.

We may need to re-review what we information we are storing with the workflow and how to appropriately display this information (e.g. what are the values of the parameters for this workflow's execution, what roi was used, etc.)?

Potentially, representing this tree with extra columns for this information (scanid, date, name, roi, etc) could be useful as well (which could hook into Qt's filtering and sorting nicely) (consider adding this as a separate issue if we want this).
