Moving .qdoc files under examples/widgets/doc

Updated those .qdoc files to refer to the new relative examples
emplacement. Images and snippets to be moved later.

Also grouped all widgets related examples under widgets.

-<h2>Gradients</h2>
-</center>
-
-<p>In this demo we show the various types of gradients that can
-be used in Qt.</p>
-
-<p>There are three types of gradients:
-
-<ul>
-  <li><b>Linear</b> gradients interpolate colors between start and end
-  points.</li>
-  <li><b>Radial</b> gradients interpolate colors between a focal point and the
-  points on a circle surrounding it.</li>
-  <li><b>Conical</b> gradients interpolate colors around a center point.</li>
-</ul>
-
-</p>
-
-<p>The panel on the right contains a color table editor that defines
-the colors in the gradient. The three topmost controls determine the red,
-green and blue components while the last defines the alpha of the
-gradient. You can move points, and add new ones, by clicking with the left
-mouse button, and remove points by clicking with the right button.</p>
-
-<p>There are three default configurations available at the bottom of
-the page that are provided as suggestions on how a color table could be
-configured.</p>
