#4 Small improvements

Hi, I added the initial colors (visible in this screenshot: https://pekdon.pekwm.se/images/posts/0.2.0-theme-updates_colormaps.png) as the variant Original (maybe you would give it a different name?). And I improved the vertical orientation of the title text a bit. I also updated the font specification in the themes for the changes in the pekwm development version (see https://github.com/pekwm/pekwm/commit/aef0b0ba731a73ae7e1ac799bff9b1c1e3210e3b). I hope you find those changes useful. Greetings, Oliver
