Enabling the loadLibrary() function into a delivery activity

Description - Simple but useful, enabling the loadLibrary() function into a delivery activity

Why is this feature important to you - I have a JS code that is included in a JS library, I need to use some functions of that library within different delivery activities, so allowing the loadLibrary() function into the delivery activity avoids having to write the same code in each deliver (I have more than 100) over and over. 

How would you like the feature to work - with this allowed function I can reuse the JS library across multiple delivery activities.

Current Behaviour - JS compilation Error, the loadLibrary function is not allowed.
