Enhancement: Ability to "Collapse all" the expanded Categories in Project view

[znb]

As a user it would be helpful to have the ability to collapse all the expanded categories in the main project view.

We have different teams working on various parts of a project and it can be a little daunting to load a project page and be confronted by a huge list of expanded categories.

If we could either load it all without expanding or have the ability to quickly collapse all the categories, it would help the teams using ASVS.

This is a really good idea, thanks Matt!
