title: PEAR HTML_Template_IT does not load Templatefile in PHP7
body: <p>I have written a CMS by myself and it works fine until PHP Version 5.6.
  Now, PHP7 is starting and I want my CMS get ready for it.
  In this CMS I use the PEAR Library, which I have upgraded to Version 1.1o because this version, so is said, supports PHP7.</p>
  
  <p>Now I have following problem with the Package HTML_Template_IT: when trying to load the template file and afterwards setCurrentBlock('meta-tags') I get the message "Cannot find this block"meta-tags'"</p>
  
  <p>Is anybody out there, who had the same problem and could solve it?
  thank you so much for your help!</p>
  
  <p>That's my Code in the index.php:</p>
  
  <pre><code>require_once('HTML/Template/ITX.php');
  $tpl = new HTML_Template_ITX(TEMPLATE_DIR);
  
  // Einlesen der Haupttemplate-Datei
  $tpl-&gt;loadTemplatefile('main_tpl.html', true, true);
  
  // Meta-Tags ausgeben
  $tpl-&gt;setCurrentBlock('meta-tags');
  $tpl-&gt;setVariable('author', AUTHOR);
  $tpl-&gt;setVariable('description', DESCRIPTION);
  $tpl-&gt;setVariable('keywords', KEYWORDS);
  $tpl-&gt;setVariable('page_topic', PAGE_TOPIC);
  $tpl-&gt;setVariable('publisher', PUBLISHER);
  $tpl-&gt;setVariable('google_verify', GOOGLE_VERIFY);
  $tpl-&gt;parseCurrentBlock();
  </code></pre>
  
  <p>here is the corresponding detail from my template-File main_tpl.html:</p>
  
  <pre><code>&lt;!-- BEGIN meta-tags --&gt;
  &lt;meta http-equiv="content-type" content="text/html;charset=utf-8" /&gt;
  &lt;meta name="author" content="{author}" /&gt;
  &lt;meta name="Content-Language" content="de" /&gt;
  &lt;meta name="description" content="{description}" /&gt;
  &lt;meta name="keywords" content="{keywords}" /&gt;
  &lt;meta name="page-topic" content="{page_topic}" /&gt;
  &lt;meta name="publisher" content="{publisher}" /&gt;
  &lt;meta name="google-site-verification" content="{google_verify}" /&gt;
  &lt;meta name="rating" content="general" /&gt;
  &lt;meta name="revisit-after" content="10 days" /&gt;
  &lt;meta name="robots" content="index, follow" /&gt;
  &lt;!-- END meta-tags --&gt;
  </code></pre>
  
  <p>that's the output in the browser:</p>
  
  <pre><code>Cannot find this block"meta-tags' 
  </code></pre>
