sdtui: enable styling of defocused selected rows
The defaults are unaffected, the row is always reverse, like it used to.
Having the deselected row just be underlined seems sensible.
It isn't currently possible to change /just/ the foreground or
the background colour of the selection, due to how ncurses works
with colours.
Bumped termo to enable requesting the appropriate events.
