Comment 2 for bug 419788

We introduced named_version 18 months ago to reduce confusion about the code name and version: maverick (10.10). I propose:
  .displayname => .codename
  .named_version => .displayname
And that the new display name only shows the version with optional LTS when the series is released. We could revert the named_version rule, but that reopens the ambiguity problem when users need

We need to add a db flag to know a series is LTS (bug 547082) and we should rename the column in the db.
