Add nanodesu-nano, which is more minimalistic and fills gaps to prevent missed clicks

[AlexFolland]

I've been using the nanodesu theme in XFCE for a couple years now, and while I love the visual style, moving my mouse to the corner of the screen often misses the button I mean to click because there's an unnecessary gap. This pull request adds nanodesu-nano, a fourth theme which changes the title bar height from 28 to 21, filling the click gap, while leaving the position of the icon graphics identical. This saves screen area and allows the user to quickly click in the corner of a maximized window without missing the click.

Maybe this should be a separate theme instead of replacing the plain nanodesu. I'm not sure. This is better to me, at least.

Thanks for creating this theme.

I made some fundamental changes to this pull request since I originally opened it. Therefore, I've updated the original message and the title with the final intentions of this pull request and deleted interim comments, for clarity.

I've now also made nanodesu-nano adapt to your overall theme's color scheme. It seemingly works well for all dark themes, but somehow many light themes don't work well. I'm using Matcha-dark-azul with nanodesu-nano and it looks beautiful with that.

@AlexFolland Sorry for late reply and thank you for putting effort into this
However, it's been a long time since I made this, TBH I'm not sure how to process with this anymore so I suggest to upload new theme from your fork instead

Thank you for responding! I already did upload this to Pling.

I wonder if you still use one of your nanodesu variants. Do you? I'm curious.

Yes of course, it's one among the first thing I do when reinstalling OS 😄

Ah, cool! Yeah, I love the minimalistic visual style that's functional with nice buttons and no wasted screen area. I like the refinement I added as well. Have you tried it yet? If so, what do you think of it?
