Annoying Bug: When we add a page to cmsms, it doesn't show up in the admin's
content list, and the page doesn't work until the cache is cleared, which we
were using the move page up/down to get new pages to work.

I tracked it down, here's the fix.

### File #1: in /admin/addcontent.php find block:
			$contentobj->Save();
			global $gCms;
			$contentops =& $gCms->GetContentOperations();
			$contentops->SetAllHierarchyPositions();
			if ($submit)
			{
				audit($contentobj->Id(), $contentobj->Name(), 'Added Content');
				redirect('listcontent.php'.$urlext.'&message=contentadded');
			}

after $contentops->SetAllHierarchyPositions(); add:
			$contentops->ClearCache();

completed block should look like:
			$contentobj->Save();
			global $gCms;
			$contentops =& $gCms->GetContentOperations();
			$contentops->SetAllHierarchyPositions();
			$contentops->ClearCache();
			if ($submit)
			{
				audit($contentobj->Id(), $contentobj->Name(), 'Added Content');
				redirect('listcontent.php'.$urlext.'&message=contentadded');
			}



#### File #2: in /admin/addcontent.php find block:
	      $contentobj->SetLastModifiedBy(get_userid());
	      $contentobj->Save();
	      $contentops =& $gCms->GetContentOperations();
	      $contentops->SetAllHierarchyPositions();
	      audit($contentobj->Id(), $contentobj->Name(), 'Edited Content');

after $contentops->SetAllHierarchyPositions(); add:
	      $contentops->ClearCache();

completed block should look like:
	      $contentobj->SetLastModifiedBy(get_userid());
	      $contentobj->Save();
	      $contentops =& $gCms->GetContentOperations();
	      $contentops->SetAllHierarchyPositions();
	      $contentops->ClearCache();
	      audit($contentobj->Id(), $contentobj->Name(), 'Edited Content');



I'm guessing that there could be other places to fix this. It's probably all
instances of $contentops->SetAllHierarchyPositions(); needs to clear the cache
after.
