[Users] GTK3 theme questions

[Brad Barnett]

Thanks everyone for their help, and Pete for the CSS.

None of this worked out for me.  Theming in GTK3 is a royal annoyance.

I got close to what I wanted, but couldn't get rid of all the extra
spacing, and just issues trying to work around (what I deem) to be a
silly and broken theming system.

Thankfully, I noticed that there is still a gtk2 maintained branch.  I
don't know how long it will last, hopefully for a few years, and thanks
to the claws team for doing so.

I mean it.  Thanks.  I'd be bananas without the gtk2 branch.

I used debian's rules directory, and tweaked things a bit, and have a
debian build/package I can employ down the road if needed.

Again, thanks claws team.
