Ability Save, Load and Edit Roles

[IAmVigneswaran]

@orchetect Suggests -

There's no way to manually add/edit/remove roles? The user might want to do that instead of dragging a project/XML.

Eventually a save/load function to store and load lists of roles and their tickbox state would be beneficial. I can envision a user interacting with this often and it would reduce tedium.

We can look into adding this feature in future.
