Code review comment for lp:~julian-edwards/launchpad/trivial-ui

= Summary =
Fix a bunch of trivial ui issues

== Proposed fix ==
 * https://bugs.edge.launchpad.net/bugs/328402 - show the ppa's signing key
fingerprint
 * https://bugs.edge.launchpad.net/soyuz/+bug/57559 - everything's already
fixed apart from the last item which is to change a heading
 * https://bugs.edge.launchpad.net/bugs/131515 - Fix inconsistent titles on
some package-related pages
 * https://bugs.edge.launchpad.net/bugs/237263 - add (pending) at the end of a
diff title's text if it's not ready to download yet

== Implementation details ==
Pretty trivial changes, I even removed some template code that was filling
heading slots!

== Tests ==
Loads involved. I already tested with -t stories -t pagetests -t doc and
everything passes.

== Demo and Q/A ==
Run this in "psql launchpad_dev" so cprov's PPA gets a signing key:
update archive set signing_key=1 where id=9;
