ARInside 3.1.4

Changed

• Built against AR API 9.1.0 (the last available version of the C API)
• When the server version is 21+ use "slow loading" for filters and escalations since ARGetMultipleFilters
  and ARGetMultipleEscalations always fail due to the API version mismatch
• When the server version is 21+, ignore "Can't decode result" errors when reading filters and escalations
  since these are Innovation Studio objects and we don't want them anyway.

Fixed

• Fixed a null reference when building the documentation if some objects failed to be pulled from the
  server (this may happen if the server is version 21+)
