Bug 31123: Display content warnings on the intranet
This patch adds handling to our XSLT processing to pass the new
`ContentWarningField` preference value to the stylesheets and then uses
that variable to add content warning notes to both the detail and search
result displays of the staff client.
Test plan
1) Run the database update to expose the new system preference
2) Set `ContentWarningField` to something sensible, like `599`
3) Add the above select field to one of your frameworks with a subfield
`a`.
4) Edit a record with that framework to add a content warning into the
record
5) Search for the record and confirm you now see `Content warning: Your
test text`
6) Click into the record detail and confirm you see the content warning
text there too
7) Bonus points: Assign a new authorized value category to the chosen
field and subfield and confirm the staff client display text is used
in the above tests.
