ms-* html generation: Provide right title for projection

ms-* html generation: Provide right title for projection

When ms-queuedaemon generates a resource-projection.html, it sometimes
does so from data-plan.pl (see proc report-plan).  This means that
ms-planner does not get a reliable indication of whether it is being
run for the plan or the projection, and the resource-project.html
sometimes claims to be the plan.

Fix with a new ms-planner option -W which tells it what to put in the
title, defaulting to the value passed to -w.

DEPLOYMENT NOTE:

The new ms-planner works with the old queuedaemon, so when upgrading,
it is OK to simply update the daemons-testing.git and then restart the
ms-queuedaemon.

If it is necessary to downgrade, rewinding to the old commit with a
running ms-queuedaemon will cause errors from the old ms-planner being
passed -w -- but these errors are trapped and ignored.  So in this
case reports will be out of date until ms-queuedaemon is also
restarted.

In either case nothing will go badly wrong.
