Change the output formato for the Export / 'CSV summary dive details'
from TSV to CSV, to make it consistent with the menu item name, and with
the other 'CSV' export function.
This was changed to TSV by @mturkia in
6c82578540,
but I could not find any discussion as to why.
Also removed replacement of the field separator in any fields, as,
according to the CSV RFC (https://datatracker.ietf.org/doc/html/rfc4180)
this is not required as long as the fields containing separators are
enclosed in quotes, and any quotes within the fields are doubled up.
Tested with a fairly large log file, and importing into Google Sheets is
working fine for the output produced.
Also made capitalisation of the Export menu items consistent.
