Zombiod Steam Workshop Downloader

#This script reads an input txt file, where the steam workshop IDs are defined (one on each line)
#It then downloads the items and copies to "mods" folder out of each of the steam workshop ID folders.
#Finally it generates the required mod line in the server ini filde for the Zombiod server. This was done as
#some mod makers appear to use a different id= line in the mod.info file to the folder name.
#Zombiod appears to read that line instead of just the folder name, so if you're getting "mod not found" errors this might be the reason.


#Define paths for various things
