tools/emacs: vterm + tramp tests…

Adding a vde/vterm that can take into account a tramp default-directory. It's not super smart still, and it needs better integration with projectile and all… … on that note, maybe vterm should be fullscreen instead of a side window 😛 Signed-off-by: Vincent Demeester <vincent@sbr.pm>
