Improve theme dependent plugin placeholders:

  - buttons_toolbar: now expect links represented by an array instead of HTML content
  - fields_toolbar: now expect a form represented by an array instead of HTML content
  - action_plugin: now expect links represented by an array instead of HTML content

Default templates updated accordingly
