Enable file naming when returning a zip file of the requested documents.
File names for each docid are provided as additional parameters named by the actual docid value that they are providing a name for. An example query string might look like:

action=read&docid=doc.1.1&docid=doc.2.1&qformat=zip&doc.1.1=fileName1.txt&doc.2.1=fileName2.jpg...

if there is no clientViewBean in the session, insert a new one - saves us from nullPointerException when using this in skins that may not be aware of the bean uses.
