Static frontend
This picks up from !882 (closed) and gets it to a usable state.
- Catches up with latest develop branch and fixes bitrot
- Adds permalinks to notice rendering
- Shows images, video, and audio, with NFSW filtering
- For notices that are part of a thread, shows all notices in the context
Of the tasks listed in !882 (closed), I felt like I am not qualified to address these remaining issues:
- Furling
- Consensus on how to override Pleroma FE
- Test strategy
I think the branch is useful as-is and could be merged to develop; these issues can be address in follow-up MRs. But if it's preferred (and if I can get some guidance on how to proceed) I could try to get them working in this MR.
This is the first Elixir code I have ever written, so some extra review may be needed; thanks!
