[r=danilo][bug=752397] Add a page (+uniquepackages) to interact with packages in derived series but not in the parent series.

This branch adds a page (+uniquepackages) to interact with packages in the derived series but not in the parent series.

== Tests ==
./bin/test -cvv test_series_views test_uniquepackages_differences
./bin/test -cvv test_series_views test_uniquepackages_differences_empty
./bin/test -cvv test_series_views test_packagesets_uniquepackages

== QA ==
- Turn on the feature flag :
    'soyuz.derived-series-ui.enabled default 1 on'
- Modify the differences in the sample dataset:
    update distroseriesdifference set status=1;
- Check out the page:
    https://launchpad.dev/deribuntu/deriwarty/+uniquepackages
    (not much to do here, except click on 'Update' to reload the page and make
     sure the differences are properly displayed)

[Данило Шеган (danilo)]

From the IRC conversation:

 rvba, is it intentional that this pages uses the same template as +localpackagediffs?
<rvba> danilos: yes
<danilos> rvba, if so, you'd probably want to rename the template so it better indicates what is it about
<rvba> danilos: that's right.
 danilos: actually the template name is distroseries-localdifferences.pt. The 3 pages sharing this templates are all used to display local differences ... of different types.
<danilos> rvba, ok, then I guess it's fine to keep the name
<rvba> yep
<danilos> rvba, the branch looks pretty good otherwise, but I have another naming question: I believe it's our practice to name all our view classes as SomethingSomethingView, so it'd be nice to change that as well
 s/as well//
 rvba, other than that, r=me
