MorphMan3: Analyze feature

These two changes seem to be all that is necessary to allow for a model (note type) to be analyzed for morphs but not actually modified.

I tested it on my subs2srs deck and it correctly flagged many cards as comprehension that before were flagged as notReady.  My known.db also grew massively and a brief visual inspection shows it to contain words that don't appear at all in my subs2srs deck.  (That is the only deck enabled in my MorphMan 3 config.)

Hope it helps a bit!  If so I can also contribute my code for stripping clozes back to parseable text.  (Another very small change.)
