Vamooses Pet Patrol

- Updated for WoW 12.1.5.
- Fix: No more false "species unreadable" warnings on a client that simply has
  fewer battle pets than retail. Pet Patrol read a short pet journal as a cold
  one, and warned twice each session that thousands of species could not be
  read. It now checks again a moment later: a journal that is still loading
  fills in, while a small one reads the same both times and is left alone.
- Fix: The world map button now takes the retail map layout on clients that
  report an unusual version number, instead of the classic one.
- Fix: The "Placeable as decor" badge and filter only appear where housing
  exists, so they no longer show on a client with housing switched off.
