fixed a bug that caused posted_date to be updated when you do *not*change the draft_p status, which was exacatly the opposite of theintention. The intention is that when you change status from draft topublish, the posted_date is set. That's how it works now.
In order for the Bug Tracker version bar to work I added the possibility for a package to stick something at the beginning of the HTML body. This is a temporary workaround. It may not work well with sites with customized default-masters. The Bug Tracker should show its version information between the header and footer instead
