Log Message:
Update to 2.6.9, requested in PR 28394.

Xquote 2.6.9 is a stable pre-release of Xquote.

The version number bump from 2.3 is caused by a simultaneous release of
Xinvest, Xquote, and QuoteFilter.

Xquote is now released under a completely free license: the BSD license.

Xquote now uses the XbaeMatrix widget to display its information in a
nicely laid out tabular format.

Basic functionality remains unchanged, but there have been quite a number
of small changes :
- use of XbaeMatrix
- simplified widget tree
- source code cleanup
- update of the user interface after each individual quote query
  (so you can see the table contents change as the information comes in)
- use of BSD license
- user interface changes (don't show the version number in the status field)
- remove sessionXq.c, merge with the Xinvest version of the same file.
- do more effort to read info from an HTTP server when it returns 400 replies.
- Figure out whether the site is using European (on hundred is 100,00) or
  American (100.00) punctuation to forward the right format to Xinvest
  in a live update.
- Avoid crashes when xquote-rc file contains invalid data.
- Fix a problem with the type list not being taken fully into account for
  other than the first server.
- Allow running Xquote 24 hours per day by setting start and end time to
  the same value.
- Document "-restore" option in the syntax() error message.
- Make the help window resizable, and respond to a single click.
