Let the operator pick, order and sort the log columns

The log showed the contest's columns and nothing else, with the country, points and multiplier columns fixed in the XAML. LogColumns now holds every field the log can show and the settings file keeps the names, left to right. A right click on a header adds or removes a column and offers the contest's own set back, a header can be dragged to move its column, and a click sorts on it. Sorting uses the field, not the text of the cell, so 9,000 kHz comes before 14,000 and the serial numbers do not run 1, 10, 2. Both grids get the same columns, so a value in the pane below sits under the column it belongs to. Removing the last column is refused, otherwise nothing could be selected.
