[zen-48] Created FormLabel view helper tests

- Suggested use cases:
  - echo $this->formLabel()->openTag() . $this->translate('Label for
    element') . $this->formElement($element) .
    $this->formLabel()->closeTag();
  - echo $this->formLabel()->openTag($element) . $this->translate('Label for
    element') . $this->formLabel()->closeTag();
  - echo $this->formLabel($element, $this->translate('Label for element'))
  - echo $this->formLabel($element, $this->formText($element),
    'append')
  - Basic idea is to allow each of the following styles of markup:
    - <label>This is a label:<input type="text" id="foo" /></label>
    - <label for="foo">This is a label:</label> ... <input ... />
    - <label for="foo"><input ... />This is a label:</label>
