[open source] make_prepatcher

Aw crap, they changed the ftp listing format. I'll have to fix the script.

Edit: Fixed. Download the latest version of the script.

So if they keep changing the format, we, less knowledgeable users, will keep being screwed? What if one day you won't feel the need to lend us helpless maplers a helping hand anymore? T_T

Thank you for fixing it though, I hope it'll work for patch 0.67~ x)
