datacheck.log: header row

[yakra]

after These entries should be in a format ready to paste into datacheckfps.csv.
and before the first datacheck entry,
a header row such as Root;Waypoint1;Waypoint2;Waypoint3;Error;Info
would provide some extra convenience for copy-pasting into a spreadsheet app such as LibreOffice.

I'll look into adding this.

Please feel free to remove the "header" printouts I have in there too if it makes it harder to use in your spreadsheet.

I let those stay; no harm in having them.
I just start copying from the 4th line of the file. Wicked easy.
