Automate room setup via Valkyrie

[Shadowfiend]

Two versions of this:

- Asking Valkyrie to create a new room in a space.
- Making Valkyrie admin in an existing room.

Valkyrie should:

• Using the space hierarchy:
  • Set the appropriate moderators for the containing space: only Valkyrie and adminbot should have admin.
  • Adjust the power settings so that moderators can do effectively everything an admin can.
  • Set the appropriate room aliases for each room (e.g. #room-name[-space]:thesis.co).
  • Set the room avatar based on the appropriate background color.
  • Automatically invite members of a space to suggested rooms.

Moderators should:

• Be able to tell Valkyrie the background color for room avatars in a new space, resulting in an update to all room avatars Valkyrie has access to update.
• Be able to request that Valkyrie withdraw herself as admin (returning admin power to the requestor).
• Be able to opt a room into or out of Valkyrie's auto-invite functionality (by marking them as suggested on the space).

To do this, Valkyrie needs to understand:

• Space hierarchy.
• Color of each space.
• Moderators at each level.
• Available permissions for a room.
• Members of a space.
• Suggested rooms in a space.
