NearFuturePropulsion Engines

Updated configs for most NFPP engines.  Three categories:
Actual flown engines - Marked as RSSROConfig = True, description, mass,
all updated.
Test Articles - When actual flight devices that haven't flown yet, but
are otherwise flight-ready, marked as RSSROConfig = True
When haven't flown yet, and flight hardware is not ready, left as
RSSROConfig = False, otherwise added stats.
Future, pie-in-the-sky configs (MPDTs, PITs, etc) The current stats are
spot-on to the theoretical predictions except the thrust is off by a
factor of 1000.  Updated the thrust values, left marked as RSSROConfig =
False, everything else untouched.

Recommend using the OrbitManipulation mod for this, will test these out
prior to submitting the pull request.
