No longer used.
Added global Parcelware page and documentation page.
Added link to Parcelware|Web.
removed uneeded constructor.
addition of usage of xml_items checkbox.
xml items checkbox
support for xml items parameter
made public
fix for items.

Note: It doesnt appear to change anything in the parcelware web items number, regardless of how many there are. This is also just simple implementations. As there are 3 ways to have products shipped, and it would be a complex endeavor to allow the user to specify what goes in what boxes ( or if they all go in 1 box ).
