#1419 Hide unnecessary script class files
It really distracting, going through source code when these classes are there. Every asset[sounds, images...etc] has a class in there and they just clutter up the source code tree view and makes it hard to navigate. It would be very convenient if we were able to select an option to hide those asset classes.
