System V Evergreen start/stop/status

These scripts add the ability to start and stop Evergreen via the
command 'service openils start' and 'service openils stop'.  To do this,
place ubuntu-precise/openils in /etc/init.d/ and make sure it has 755
for its permissions.  Then, move ubuntu-precies/start-openils and
ubunut-precies/stop-openils to /usr/local/sbin/ and make sure they have
755 as well.

Finally, give the openils service runlevel priorites.  You can do this
with the following command: 'update-rd.d openils defaults 88 13'

I have tested this with master on Ubunut 12.04.  It is also working,
with modifications on Sitka's 2.4 systems.
