[PATCH 1/2] dim: Workaround Outlook + Patchwork mess.

[Rodrigo Vivi]

Patchwork has a own identity that doesn't respect the author configuration.
It automatically changes the author to whatever it was last seen on
the public mailing list.

In case the response came from an outlook server the author identity
inside patchwork will get changed to Last, First.

We have authors that respond emails to public mailing list using
Intel emails. Even non outlook users can end up having this trouble
because the Evolution can be setup with EWS, for instance.

Since we could never fix patchwork for real to respect users
choice we can workaround it here when applying the patch.

It is really unlikely that users will have author and signed-off
configured one with "First Last" and other "Last, Name". So if
we identify this case when applying the patch let's be smart
and fix it up.

I have merged many patches recently where this happened. When
asking the authors the response was always the same, please
respect the sign-off and use "Name Last".
