File paths need to be Url decoded when extracting

[Tadas]

As the title says, when files in a module have special characters (e.g. a space), they will be urlencoded during packaging. During extraction they need to be decoded.

Makes sense! Good catch!

@Tadas haven't forgotten about this, but I've been rewriting the module in C# and will have this fix included.
