* web: initial implementation of profile RSS feed
* re-work RSS feed to use DID in URL, not handle
Shouldn't have RSS feeds break when folks change handle.
* rss: tweak XML
- handle missing content (PWI opt-out) better
- use opengraph "article" and "profile" types, not just website for everything
- fix timestamps, and used indexed at not created at
Probably still not perfect, but better.
- don't user avatar image. use banner for profile and post img, or
nothing
- most twitter metadata fields were redundant; twitter will parse out
opengraph ("og:"), so don't duplicate those
- add regular HTML description (for google, etc)
- include URI
- actually include text
