[Remind-Fans] Rebrand to GNU Remind

[Dick]

Hi,

I think it would be very helpful to rebrand "Remind" to "GNU Remind".
Currently it's really hard to find "Remind" on search engines.

Especially when you're looking for something related to Remind the
search results are really bad.

For example, try searching for:

- remind macos
- remind calendar
- remind android
- remind examples
- remind wiki

Adding "gnu" to the search terms is already a bit better but would be
much better if "GNU Remind" would have been used consistently.

Slightly related; I'd also recommend to add remind to some
GNU software lists online.

I hope this helps, just a random idea from me.

Kind regards,
Dick
