v0.16.0-rc3

Hiya! Third RC for 0.16.0!

No db migrations or config file changes between v0.16.0-rc2 and this version, so upgrading is as simple as updating your docker container or stopping GtS, untarring the release, and starting GtS again.

For instructions to update to this release candidate from versions < v0.16.0-rc1, see the v0.16.0-rc1 release candidate notes, but replace v0.16.0-rc1 with v0.16.0-rc3 throughout.
