MediaProxy whitelist setting now supports hosts with scheme

added deprecation warning about using bare domains

CHANGELOG.md

@@ -12,6 +12,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 - MFR policy to set global expiration for all local Create activities
 - OGP rich media parser merged with TwitterCard
 - Configuration: `:instance, rewrite_policy` moved to `:mrf, policies`, `:instance, :mrf_transparency` moved to `:mrf, :transparency`, `:instance, :mrf_transparency_exclusions` moved to `:mrf, :transparency_exclusions`. Old config namespace is deprecated.
+- Configuration: `:media_proxy, whitelist` format changed to host with scheme (e.g. `http://example.com` instead of `example.com`). Domain format is deprecated.
