NEW FEATURE PLS - Better Position List Headings

[routeconverter]

I've noticed different formats use different names for the same data fields, so how about once the format of a loaded file is determined, the position list field name titles reflect the actual field names for that format.

I found the title "Description" for what is the GPX field "Name" a bit confusing.

Well, RouteConveter is not a GPX tool. In that case I would have choosen the GPX element names for the user interface.
RouteConverter is targetted at planning, conversion and simplified usage. This means it uses generic names for the data fields in the 75+ supported file formats. Switching to file format specific names would cause more confusion.
