Removing roles

[fungl164]

Hi,

Right now it is not possible to remove or reset role definitions. It would be awesome to have the following utility functions if possible:

// Remove role definitions
func (role *Role) Remove(name string) {
    delete(role.definitions, name)
}

// Reset role definitions
func (role *Role) Reset() {
    role.definitions = map[string]func(req *http.Request, currentUser interface{}) bool{}
}

Msny Thnxs!

I think it is not necessary to remove a defined name, you could just create another roles set.
