Reading/writing pages now works with revisions.

However, revisions break deletion and searching needs fixing.

"Deletion" will be by setting a "deleted" flag in the experiments table (we don't actually want to delete our audit trial)
Change deletion process to only change the status of the experiment. Like a recycle bin.

Statistics reflected correctly in profile and in counts in a couple of places.
Search gracefully handles deleted items and works with revisions. Searches only the latest revision.
Enable PDF generation with revisions system.

Looking towards introducing chemical structures. So we now have "experiment types", including chemical ones.

This might want to be a database thing, like "items" and "templates" are now. In fact, maybe make "chemical" a bool on templates.

Also have chemical structure drawing tool in edit page. It's there but it doesn't do anything, and it breaks the tinymce editor.
