Convert notifyflags options to lists as supported by the init script, so multiple options can be chosen.
Add SYSLOG default option to individuals notifyflags instead of deprecated flag 1|0.
Add comment for defaultnotify and individuals notifyflags about possible values.

Instead of making POWERDOWNFLAG an uci option the user can
only change it via initscript edits.  This avoids chance for users
to miss the required change to nut-driver when setting an UCI option
for nut-monitor which results in failure to do FSD on the UPS.

By default use a non-privileged user that is different than
the server or driver (when they are running non-privileged).
This is recommended by upstream.

Forced shutdown of the UPS was not actually happening before
due to lack of specific commands doing the shutdown.  This
(and the nut-driver initscript) fix that.

This fully procdifies nut-monitor, which fixes some issues with
very slow restarts (due to /lib/functions/procd.sh using a very
long delay for non-native scripts doing restart) as well as gives
respawning, etc.

With a LuCI app (of which I have one written) ucification makes
sense (and is in fact needed), so ucify the initscripts.

Also, rather than making selection of things to include an image
a matter of selecting compile-time config options, make optional
things into seperate packages that are built in default builds,
and leave selection of what to include or not up to the user
(e.g. using ImageBuilder, or adding packages via opkg).
