Improve redirect to avoid removing the savemsg which can be useful
and start to use the service array instead of the plain name.  This
is going to help with moving all the start/restart/stop info into
the service array creation for base services as well as plugin
services.

fix relayd startup/restart (ref #780)

Most of the time, there is no return value from the functions,
sometimes $retval is not evaluated, and sometimes it just seems

It's also not practical, because there is no no notion of a
rollback that would have to ensue in such cases.

GUI sorting for now should be new, update, reinstall, remove.  Later
