Mention emacs-lucid in section "As a daemon"

It might be worth mentioning emacs-lucidAUR in the section on running emacs as a daemon, due to the following bug that Emacs warns about when started in daemon mode:

Warning: due to a long standing Gtk+ bug
Emacs might crash when run in daemon mode and the X11 connection is unexpectedly lost.
Using an Emacs configured with --with-x-toolkit=lucid does not have this problem.

In particular, when connecting to the emacs daemon from multiple X sessions (e.g. via VNC or multiple tty's), the default (GTK) version of emacs will crash when an X session is closed. The lucid version of emacs does not suffer this issue.
