Made a new tentative.html view for tentative matches.

All matches made algorithmically are put in the tentative matches list
and await confirmation before they are used to expand the model.
Fix tentative match list.

Previously, you could confirm a match, then before it was processed,
it would be re-added to the list, then you'd not be able to confirm it 
again, and it would get stuck there. Now it should clear it out whenever
it is matched.
Fix for if inert species is last in model.

Problem was you would 'continue' but have nothing left to do,
and avoid the "wait for user input" part, so finish.

Now it enters the "wait for user input" more readily.
Tweak html for index and header.
Added some confirmed species to a few models.
