Patch to get block 'pages' tags and other nested tags loading properly

I have a custom pattern containing a block specification as follows:

    <block id="user-3">
      <status>1</status>      
      <weight>-4</weight>
      <region>left</region>
      <visibility>1</visibility>
      <pages>
        <path>[front]</path>
        <path>test</path>
      </pages>
    </block>

The problem was the 'pages' element wasn't being loaded properly. Specifically, _patterns_rearrange_data() wasn't re-arranging it properly because the 'pages' tag only contained a nested element and no inner text.

The patch below fixes this and ensures that this element (and indeed all other such nested elements for other tags) get re-arranged, and thus loaded properly.
