  The templatetag "textblock" lets you embed text-snippets (like for example the help section of a page)
  into a template.
  
  It accepts 2 parameter:
  
      slug
          The slug/key of the text (for example 'contact_help'). There are two
          ways you can pass the slug to the templatetag: (1) by its name or
          (2) as a variable.
  
          If you want to pass it by name, you have to use quotes on it.
          Otherwise just use the variable name.
  
      cache_time
          The number of seconds that text should get cached after it has been
          fetched from the database.
  
          This field is option and defaults to no caching.
  
  Example::
  
      {% load textblock_tags %}
  
      ...
  
      {% textblock 'contact_help' %}
      {% textblock name_in_variable %}
  
  The 'flatblock' template tag acts like an inclusiontag and operates on the
  ``textblock/textblock.html`` template file, which gets (besides the global
  context) also the ``textblock`` variable passed.
  
  Compared to the original implementation this includes not only the block's
  content but the whole object inclusing title, slug and id. This way you
  can easily for example offer administrative operations (like editing)
  within that template.
