Add rename feature to base names and role profiles

[Antr4cite]

Bases and role profiles can't be renamed. I don't know if this will be added in the the future but it should be.

And make a confirmation popup appear when we press the "Change Default Loadout".

Agree with both suggestions.

[GizmoGomez]

I agree as well. I'd like to be able to delete roles as well, so I can get rid of unneeded fluff.

+1 here.
