[Users] Adding latest Google Policies to Win32 Version of Claws

[Rosemary Lockie]

Hello,

I have noted Michael Rasmussen's message to say that the latest git version has been
adopted to the latest Google policies, and have cloned it to investigate what changes
are needed to my clone of the claws-win32-installer to build the Win32 version of Claws.

My assessment is that I need to replace (at least) oauth2.c in 

~/claws-win32-installer/packages/claws-mail-3.19.0.tar.xz 

with the equivalent from the latest git.

However I suspect there may be other files as well?

Before I embark on this, can someone please advise if it is likely to be as "simple", as
to replace/update just a few source files?

Thank you.

Kind Regards,
Rosemary Lockie
