When using preupload slide url in create request, http redirects are not followed.

[GoogleCodeExporter]

If you send a create request to BigBlueButton with a preupload slides document 
like the following:

<?xml version="1.0" encoding="UTF-8"?> 
<modules> 
    <module name="presentation"> 
        <document url="http://example.com/sample.pdf" /> 
    </module> 
</modules>

and the url given is an HTTP redirect (for example, HTTP codes 301, 302, 307), 
BigBlueButton does not follow the redirect. Instead it saves the contents of 
the redirect page, which is often an html or plain text message automatically 
generated from the server.

The result is a corrupted slide which does not display properly and may prevent 
recording processing.

Ideally, BigBlueButton should follow redirects on the preupload slide url.

Here's a possible way to follow redirect.

And use org.apache.commons.io.FileUtils.copyURLToFile(URL, File) to save the 
file.

Check if URL redirects and follow redirect if it does.

Check response if 200 then download the file.
