This theme focuses more on hues than saturation. Aside from that it's
not very special versus the stock themes.
Also add an alias for taskwarrior-tui because it's sometimes useful.
~/bin/statusbar is a python script on my desktop but on a work machine I
will likely not be using the same script, so make this execute
~/bin/statusbar instead of invoking `python3 -u` on it. Then I can just
repoint the symlink to whatever generated my statusbar.
