Error after recent patch update

[YEnthalpy]

Hi KakaZzzz, could you please take some time to fix the addon? I think it is caused by Blizzard deprecating old APIs.

The error message is shown below. Thanks very much!

AutoEquip/core.lua:319: attempt to call global 'GetContainerNumSlots' (a nil value)
