#1506 Generalize WatchDate to be WatchPrePub

[Ahasuerus]

We have a "WatchDate" template and a linked cleanup report which help keep track of pub records with publication dates from questionable pre-publication sources. The template is currently found in 20 publication records.

Based on our experience with pre-publication data, it would be useful to have broadly similar functionality for questionable pre-publication covers. We could accomplish this goal by creating another template/cleanup report pair, but it's been suggested that creating a generic template/cleanup report pair for questionable pre-publication data would be a better long-term solution.

Here is the current proposal:

Create a new template, "WatchPrePub", as a replacement for "WatchDate".
The new template will be used for all types of "questionable pre-publication data".
The new template will take a parameter indicating which field's (or multiple fields') data is questionable.
The new template will expand to something like The following data is based on questionable pre-publication information and may be incorrect: [parameter, e.g. "publication date" or "cover and publication date"].
The linked cleanup report, which currently displays the publication title and the publication date, will have a "Questionable Field(s)" column added. It will also let editors re-sort the table by publication name, by publication date or by field name similar to the way the Publication Series page works.
