Subject: [PATCH] Bug 20692: Extreme toggle checking for plack

TEST PLAN
---------
sudo koha-plack --disable
sudo koha-plack --disable
sudo koha-plack --enable

sudo koha-plack --disable
echo $?
sudo koha-plack --disable
echo $?
sudo koha-list --noplack
echo $?
sudo koha-plack --enable
echo $?
sudo koha-plack --enable
echo $?
sudo koha-list --plack
echo $?

git bz apply 20692
sudo perl ~/misc4dev/cp_debian_files.pl
then repeat the test.

It should also be noted, because the enable
and disable are now split, if for some reason
they become out of sync, an enable or disable
should correct them.

Because these are bash scripts, the test tool
(/home/vagrant/qa-test-tools/koha-qa.pl)
does not apply.
