Date: Sat, 26 Sep 2020 19:32:16 +0300
Adjusted MediaProxyControllerTest to gracefully fail on missing dependencies. Installation docs update.
Added ffmpeg/imagemagick checks to launch checks (if media preview proxy is enabled). Added documentation on installing optional media / graphics packages (imagemagick, ffmpeg, exiftool).

Not only does this make it much easier to deploy changes you make, as you can commit and pull from upstream and all that good stuff from the comfort of your local machine then simply `git pull` on your instance server when you're ready to deploy, it also ensures you are compliant with the Affero General Public Licence that Pleroma is licenced under, which stipulates that all network services provided with modified AGPL code must publish their changes on a publicly available internet service and for free. It also makes it much easier to ask for help from and provide help to your fellow Pleroma admins if your public repo always reflects what you are running because it is part of your deployment procedure.
