Aegis Guild Hall

### Changed

- Updated for WoW 12.1.5.

### Fixed

- **Aegis no longer asks the server about houses on a client where housing is
  switched off.** Opening Manage, the Vault, Neighborhoods or a judging tour
  asked the game about members' houses and your guild's blueprints. On a
  client without housing that request can drop your connection a few seconds
  later. Aegis now checks whether housing exists before asking. Where it
  doesn't, the Neighborhoods tab, the Blueprints tab in the Vault and the
  house-visits challenge are hidden, and the Vault opens on Items. When no
  officer has set a challenge there, the week defaults to Quests turned in
  rather than House visits, which nobody could score. The officer's list of
  games to pick from also leaves out Mythic+ and Dungeon Finder runs there,
  since WoW: Forever has neither.
- **Guild applications are only fetched when the Guild Finder is switched on.**
  Aegis used to ask for the applicant list whenever the finder's functions
  existed, which is every client, rather than when the finder itself is on.
- **No more Lua errors from Blizzard's House Finder tutorial.** If you had never
  finished the House Finder's tutorial, a neighborhood scan could set off a
  stream of errors from Blizzard's housing tutorial that lasted until you
  reloaded. The tutorial expected Blizzard's House Finder window to exist, and it
  didn't until you opened it yourself. Aegis now loads that window, hidden,
  before asking the game about neighborhoods.
