Infinite loop in columnizeIt where destroyable items are empty

[zeffrin]

Ran into issue with infinite loop on the while at line 532.

$destroyable.contents().length gets stuck on 2, and both of those items are empty
Then on line 564 goes in here and appends more emptyness to $col.contents(), goes in every time etc

Hacked a fix as so, insert line 585 (end of while loop)
if($destroyable.contents().length > 0)
{
for(int i = $destroyable.contents().length - 1; i >= 0; i--)
{
if($destroyable.contents(i).length == 0)
$destroyable.contents.remove(i);
}
}

I would submit pull request but I suspect there's going to be a root cause/better place to fix this

Thanks

ok that fix isn't right actually, should've been var there but not only that..

I'm having same problem again now except both destroyable.contents() hold 27 non ascii chars
