Add options to hide add/edit buttons on associated fields


There are cases where you may want to authorize access to a model, but not display the add/edit buttons in an associated form field.

e.g. Allow the user to add/edit teams, but remove the inline buttons on the player form.

    config.model 'Player' do
       field team do
          inline_add false
          inline_edit false
      end
    end
