Merge lp:~allenap/launchpad/dd-initseries-bug-727105-architecture-picker into lp:launchpad

[Gavin Panella]

Updates test.css to import sam/skin.css so that javascript unittests
are readable.

Registers the view and a custom template for the +initseries
page. There is a very minimal test for this right now; the view is
trivially simple so there's not much else to do.

Exports DistroSeries.architectures, a collection of DistroArchSeries
related to the series.

Creates a new javascript widget, ArchitecturesCheckBoxListWidget, that
shows checkboxes for a given set of choices. This extends another new
widget, CheckBoxListWidget, that will itself probably be rebased in
subsequent branches (the form on that page is not yet complete). The
new architectures widget is also plumbed in. To try it out:

  - Go to https://launchpad.dev/ubuntu/hoary/+initseries

  - Change the options in the series drop-down box. Not all of them
    have any corresponding DistroArchSerieses.

[Benji York (benji)]

This branch looks really good.

I only noticed one small thing: the "description" attribute of
"derived_from_series" would fit on one line if so desired.

review: Approve (code)
