Code review comment for lp:~edwin-grubbs/launchpad/bug-426899-ppa-links

Summary
-------

Instead of having multiple links for "Related projects", "PPA Packages", and
"Uploaded packages" on the person/team index page, there is now one "Related
software and packages" link that takes you to the +related-software page where
you can navigate to all the other pages.

The links on the +related-software page are now only displayed when there
are entries for "Uploaded packages", etc.

Tests
-----

./bin/test -vv -t xx-person-packages.txt

Demo and Q/A
------------

* Open http://launchpad.dev/~mark
    * Should have a "Related software and packages" link underneath the branding.
* Open http://launchpad.dev/~mark/+related-software
    * There should be five links at the top of this page, and the link for
      the page you are on should be delinkified to show which page you are on.
        * Related software
        * Maintained packages
        * Uploaded packages
        * PPA packages
        * Related projects
* Open http://launchpad.dev/~guadamen/
    * Should have a "Related software and packages" link underneath the branding.
* Open http://launchpad.dev/~guadamen/+related-software
    * Should just show the "Related software" link which is delinkified (plain
      text) since guadamen doesn't have any packages.
