ebayShopper d48c9070e8 Revert the last two commits
This reverts commits b5f3f30 and 3e0ddef.

Discussed with oiad on discord:
- BIS_fnc_areEqual is much slower than short string comparisons
- String in array form is three times longer, which means more data sent over the network

This way keeps authKey as a string and still avoids pvval kicks.
