Poking around in the CF app I noticed that the auth.py module for integrating with
the community authentication was out of sync with the copy in the main pgweb repo.
Turns out the copy in the CF app is the most up to date as it has fixed the email
address in the account merging support email template. The attached patch merges
the changes from the CF app copy into the one in the pgweb repo. Unless there are
objections I plan to apply this soon.
This also fixes an adjacent typo spotted in the process.
