use pupopt as an array
quote some more places

That is, everytime a run exits with a non-zero exit code (as handled by
puppetgo, so puppet exit 2 -> 0), the next run starts with a delay of up
to 240 seconds.

That should spread out the load of repeated tries to run that overload
the (already loaded) puppetmaster machine, as such helping the whole
plethora of servers finally get their run done...

Not nice, but works.

Thats a behaviour change, prior to this human meant "run, even if there
is no change in git". Now it checks git changes. It also adheres to
/nopuppet.

Humans who want to have a run now, no matter what, can use -d as before.

When /run not exist, look if /var/run or /var/lock does and
then use thwt for the LOCKFILE and the store of the last git revision.

Branches, as such environments, can disappear for a short while when
they get rebased and "force" pushed using something like

git push origin :branch && git push origin branch

Machines should still use them in such a case, so only switch back to
production if the branch is missing in two puppetgo runs.
