Fix getPubConfig so it handles copy archives

[Julian Edwards (julian-edwards)]

= Summary =
Fix getPubConfig so it handles copy archives

== Proposed fix ==
getPubConfig() is a function in the archivepublisher module that returns a
publisher config for the, err, publisher. The config varies depending on what
type of archive is being published. Note that this is not a canonical.config
object, it's some old Soyuz crack.

This branch adds the necessary changes to make publishing of Copy archives a
reality. It's another of the many branches I'm doing to fix bug 520520.

== Implementation details ==
It's utterly trivial. Read the diff :)

== Tests ==
bin/test -cvvt publisher-config.txt

== Demo and Q/A ==

= Launchpad lint =

Checking for conflicts. and issues in doctests and templates.
Running jslint, xmllint, pyflakes, and pylint.
Using normal rules.

Linting changed files:

<salgado> bigjools, I was just wondering if it'd be possible to use a newly created distribution in that test, to have it not depending on any sample data
<bigjools> salgado: that would be quite a lot of work :/
<salgado> I imagined
<bigjools> the other tests in the file all do the same thing
<salgado> bigjools, do we need to have the suffixes hard-coded there? can't we take them from a constant somewhere?
<bigjools> salgado: that's the only place they will appear - is there a benefit to doing that?
<salgado> in that case, no

review: Approve (code)
