Add folders to the roles tab

For community servers that allow user assignable roles such as Colours and Interests, it gets really hard to navigate a singular long list of roles.

It would be extremely nice to get the same kind of treatment that the channels list did with the categories update.
this would allow us to keep the same hierarchy system for roles, but add the ability to organize things into neat Categories/folders. Instead of having to make special blank roles as dividers adding to the length of the clutter and the disorder of the list.

As a server owner that wants the user to have many options for themselves as far as roles, it becomes increasingly difficult to make a new role and keep everything organized with the current system as it stands. This complication used to exist for channels and adding categories improved the situation instantly. 

Please add the option to create organization Folders/Categories in the Server role management window.
