title: Check if an select option exists based on text in jQuery 1.7
body: <p>So I have the following piece of HTML:</p>
  
  <pre><code>&lt;select id="sel"&gt;
  &lt;option value="0"&gt;Option1&lt;/option&gt;
  &lt;option value="1"&gt;Option2&lt;/option&gt;
  &lt;option value="2"&gt;Option3&lt;/option&gt;
  &lt;option value="3"&gt;Option4&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>How do I check to see if #sel has an option based on the text value? ("Option1")</p>
