Project status update

[Michael Mayer]

Quick update on our recent progress:

1. Our license has changed from Apache 2.0 to GPL v3 (see discussion
on this list).

2. We've recently spent a significant amount of time presenting
PhotoPrism to potential contributors and sponsors. While we love
coding, we felt this is important too. Link to slides we created for
this: https://photoprism.org/downloads/PhotoPrism.pdf (feedback
welcome)

3. Our new Patreon page is now online at
https://www.patreon.com/photoprism and we've also added a SPONSORS.md
file. This is a first attempt to cover our expenses and hopefully find
a way to work full-time on this. Our focus are corporate sponsors and
foundations, we don't want to ask for donations from individuals at
the moment.

4. I've found additional links on how to fund open-source projects
today, see https://github.com/photoprism/photoprism/wiki/Open-Source
(who can figure out if any of this makes sense for us?)

5. Andrea collected lots of interesting links to related research, see
https://github.com/photoprism/photoprism/wiki/Research - thank you :)

6. Our 2nd Meetup in Berlin will take place on 12/12/2018. See
invitation on this list for full details. I've also posted this in
#berlin on gophers.slack.com. Looking forward to seeing you tomorrow
evening!
