Page handler prints directly the pages

[sembrestels]

There is no function to take the data that Elgg sends to the browser.

If you want to get it you have to do this:

ob_start();
page_handler($handler, $path);
$out = ob_get_contents();
ob_end_clean();

We could avoid this using the function different, printing page contents outside the function.

echo elgg_page_handler($handler, $path);

And maintain the page_handler for backward compatibility.
