Patch: Update FilteredDropdownSet so that returnLabel can also be a method instead of a field.

[hdrlab]

I needed to use a FilteredDropdownSet, but the label in the dependent dropdown box came from a method (e.g., getFullName()) instead of a single database field. This required a small modification to the FilteredDropdownSet. I think that this might be useful for others too.

The change is too small for me to bother forking the project and sending a pull request, so here's the patch:
