Selects <feckless-fieldset> as the default tag for field lists in Hobo. The previous version is still available in <field-list-v1>. To revert to this usage, add to your application.dryml:

<def tag="field-list">
  <field-list-v1 merge/>
</def>

You can use feckless-fieldset in a manner stylistically more similar to field-list-v1 via:

<def tag="field-list">
  <feckless-fieldset class="horizontal" merge/>
</def>
