- Don't prompt about processes when killing buffer
- Hide modeline in vterm buffers (doesn't do anything useful and would
be consistent with settings for eshell and term modules).
- Refactor +vterm/open & +vterm/open-popup
- Add Emacs window redraw hack to force vterm to redraw, fixing
artefacting in some edge cases.
- Fix ansi-color-names-vector when solaire-mode is present, otherwise
you get a mismatched background in vterm (and other terms).
