big update, please read carefully!

permission modeling has been moved from statically defined in your bot
config to a cascading model, as set by your parent room or space.

when upgrading:
- ensure your bot is an admin of your space or parent room
- run the `!community sync` command to migrate your admins and
  moderators to your parent space, and clear out these fields in your
  config
- optionally run `!community setpower` to ensure power levels are set in
  all space rooms according to your parent space

if you have legacy rooms with incorrect permissions, you can now upgrade
them easily with the `!community replaceroom` command. see the readme
for more information.
