collect unmatched tokens

[stereosteve]

Hello Kaspar,

One thing that might be nice is the ability to collect the extraneous tokens, so that if user enters 100nF 0603 50V Kemet, the Kemet token could be used for full text search.

This is a pretty hack-y way to do it, and it breaks the return behavior of {} for no match. I've not used Nearly before, so believe there is probably a better way to do this, but thought I would create PR just to get your thoughts.

Hi Steve, I was playing around with something similar quite a while back on the return-ignored branch. It did what you implemented but also checked if any input caused no change to the output. I believe it still fails on some edge cases.

There is a demo up as well. Should have opened a pull-request for visibility. The way you just add it as a prop on the return object is neater more backwards compatible than what I did though.
