Detail view UI: Support for text action buttons

Currently, only icons are rendered on detail view actions. This change
adds support for showing a text label next to specified actions, which
has a button appearance. This is to allow certain actions to be more
visible, in the case where an icon isn't clear enough.

To make an action have a text label, add a 'textLabel' attribute to
the action properties:

editVpc: {
  label: 'Edit VPC',

  // textLabel property
  textLabel: 'label.configure',

  action: {
    ...
  }
}
