title: Issue with QHash
body: <p>I been trying and trying to get this to work but it just refuses to work. I read the QT documentation and I'm just unable to get the insert function to function. When I build I get the following complication errors</p>
  
  <pre><code>/home/mmanley/projects/StreamDesk/libstreamdesk/SDDatabase.cpp: In constructor 'SDDatabase::SDDatabase()':
  /home/mmanley/projects/StreamDesk/libstreamdesk/SDDatabase.cpp:27:44: error: no matching function for call to 'QHash&lt;QString, SDChatEmbed&gt;::insert(const char [9], SDChatEmbed (&amp;)())'
  /usr/include/qt4/QtCore/qhash.h:751:52: note: candidate is: QHash&lt;Key, T&gt;::iterator         QHash&lt;Key, T&gt;::insert(const Key&amp;, const T&amp;) [with Key = QString, T = SDChatEmbed]

  </code></pre>
  
  <p>here is the header file:</p>
  
  <pre><code>class SDStreamEmbed {
          Q_OBJECT
      public:
          SDStreamEmbed();
          SDStreamEmbed(const SDStreamEmbed &amp;other);
  
          QString FriendlyName() const;
  
          SDStreamEmbed &amp;operator=(const SDStreamEmbed &amp;other) {return *this;}
          bool operator==(const SDStreamEmbed &amp;other) const {return friendlyName == other.friendlyName;}
  
      private:
          QString friendlyName;
  };
  
  Q_DECLARE_METATYPE(SDStreamEmbed)
  
  inline uint qHash(const SDStreamEmbed &amp;key) {
      return qHash(key.FriendlyName());
  }
  </code></pre>
  
  <p>and the implementation</p>
  
  <pre><code>SDStreamEmbed::SDStreamEmbed() {
  
  }
  
  SDStreamEmbed::SDStreamEmbed(const SDStreamEmbed&amp; other) {
  
  }
  
  QString SDStreamEmbed::FriendlyName() const {
      return friendlyName;
  }
  </code></pre>
  
  <p>and how I am invoking it</p>
  
  <pre><code>SDChatEmbed embedTest();
  ChatEmbeds.insert("DemoTest", embedTest);
  </code></pre>
  
  <p>and the definition of ChatEmbeds</p>
  
  <pre><code>QHash&lt;QString, SDStreamEmbed&gt; StreamEmbeds;
  </code></pre>
