Add host groups (one tmux window per group) and lightdm --autologin

Browse Source 
SOCKTOP_GROUPS splits hosts into ';'-separated groups, each its own tmux
window with an optional @layout. The carousel walks group overview -> each
pane zoomed -> next group overview. SOCKTOP_HOSTS still works as one group.

install.sh --autologin writes a lightdm.conf.d drop-in; uninstall removes it.
