Updater 4.3
Changes: -The script doesn't touch the user.js file until it really has to. -The merge function is a bit smarter parsing files, at no significant cost. See examples below. -Minor syntactic changes here and there. Additions: -New -multiBackups argument. I personally intend to use it to compare files and quickly review changes.
