title: Mantis custom field "date" giving odd default values
body: <p>For collecting <strong>Date of Manufacture</strong> when customers open new issues, I added a custom field to my Mantis install (cur ver) with the type "date". I did not specify default values or possible values.</p>
  
  <p>Mantis creates the following HTML on its own:</p>
  
  <pre><code>&lt;tr class="row-2"&gt;
      &lt;td class="category"&gt;&lt;span class="required"&gt;*&lt;/span&gt;Date of Manufacture&lt;/td&gt;
      &lt;td&gt;
          &lt;select tabindex="6" name="custom_field_3_year"&gt;
              &lt;option value="0"&gt;&lt;/option&gt;
              &lt;option value="2011"&gt;2011&lt;/option&gt;
              ...snip...
              &lt;option value="2019"&gt;2019&lt;/option&gt;
          &lt;/select&gt;
          &lt;select tabindex="7" name="custom_field_3_month"&gt;
              &lt;option value="0"&gt;&lt;/option&gt;
              &lt;option value="1"&gt;January&lt;/option&gt;
              ...snip...
              &lt;option value="12"&gt;December&lt;/option&gt;
          &lt;/select&gt;
          &lt;select tabindex="8" name="custom_field_3_day"&gt;
              &lt;option value="0"&gt;&lt;/option&gt;
              &lt;option value="1"&gt;1&lt;/option&gt;
              ...snip...
              &lt;option value="31"&gt;31&lt;/option&gt;
          &lt;/select&gt;
      &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>The month and day bits are ok, and we don't particularly care if the user inputs an impossible day like February 30th.</p>
  
  <p>However, the years are screwed. For whatever reason it starts at <strong>2011</strong> and runs through <strong>2019</strong>. Because it's a select box you cannot manually input dates. </p>
  
  <p>What is determining the year range?
  How can I set it to something appropriate?</p>
