Hi,

continuing with #275 I noticed, that when I have one gear set with a shirt equipped and the other one with no shirt and I want to switch the item set I get again the error message:
"Swap stopped. Something is on the cursor"

Even with changing line 283 to if swap[k]==0 or swap[k]=="0" then -- if intended to be empty

Switching between sets, where always no Shirt is equipped causes no error message.
Same applies for switching gear sets with always a Shirt equipped.
So only the combination Shirt <> No Shirt causes the aforementioned error "Swap stopped. Something is on the cursor".

A fix would be awesome.
