Vue binding for environment role selections.

The environment name will be grayed out until something besides the
default "no access" is selected.

Small changes to the application member subforms:
- filter for "None" as a string
- have nested forms inherit from FlaskForm; each nested form adds its
  own validation error flash otherwise if there are validation problems
