Ariel Backenroth 08f2795110 - showing uploaded files in the summary screen for create web content
- more careful management of the formprocessing session.  need to actually have a session management object so as to clear the upload file list.
- fix for form selection dropdown in create web content
- properly updating uploaded files from edit xml
