Fixing bug '#19 Enable notifications on file upload'. Modified patch #534 to make it actually work on HEAD. Should work for Oracle as well but not tested on that db yet. This could do with some cleanup, and i18n-ization.
merge changes on oacs-5-1 branch to head, changes between jcd-merge-20040420 and jcd-merge-5-1-20040517 were merged, head pre changes is jcd-merge-pre-20040517 and post is jcd-merge-post-20040517
