Donation Reminder

Is your feature request related to a problem? Please describe.
We are not currently getting enough funding for rfswarm, it would be great if we could get enough funding to employ a team of full time developers.

Describe the solution you'd like
Add a donation reminder to rfswarm, like the ones other open source software has (e.g. Thunderbird), potentially remind people once a month? or once every 3 months?
Also we need to have a "registration" code system for people who have donated to prevent this reminder showing up.

After giving this some thought I think rather than a periodic reminder and a registration system I'll just do a one time reminder on first launch for now. It's much simpler to impliment

I did figure out how I could do the registration system, though:

• have a ods file with emails and date of last donation (would need manual update)
• run a macro in the ods file to generate a JSON file
  • the JSON keys would be a md5 hash of the donator's email address
  • the value would be the timestamp when the next reminder is due (calculated future value based on date of last donation)
• gui app would need a field where people enter their donator's email address (about screen?)
• gui app would need to
  • md5 hash the email
  • retrieve the next remind date from the json stored somewhere (didn't figure this out yet) and compare to today's date

Ended up setting the reminder interval to 1 year, I think this will be a good balance between often enough to remind people and not often enough to annoy people.

Merging into release branch v1.4.0
