server/posts: auto convert GIFs to WEBMs/MP4s

- Default setting is false for both conversions, as this will require
  additional resources of the server, but is bandwidth friendly for
  viewers
- WEBM conversion is slow, but better quality than MP4 conversion with
  a typically smaller file size
- Tags are copied over from the original upload
- Snapshots are generated for the new auto posts
