Metacat

use the read() method instead of manually calling with parameters

refactored the sessionService to use a correct singleton initialization scheme. Added true authentication to ResourceHandler.

Change sanparks skin to log in with browser session instead of metacat client session so session can be validated on other pages.

Change location of PropertyService to properties directory

match the "qualified" property name

use the docid, not the filename when updating this node.

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.

prevent null pointer exception when there are no nodes found (just an empty list)
