Very minor typo fix, you probably won't even notice.

Great Scott! A new update!

Update changes for Lua Error Fixer:
A / B, where A or B is nil: Now always returns A.
Now returns 1 for A ^ nil.
Number and string comparators now have the same metatable.
- Note: Still doesn't help to fix the bug, unfortunately.

Appended some warning text to the Lua Error Fixer.
