Testing background stripping idea.

Testing something in response to Kelly's PR - https://github.com/mpelletier-vhl/Pretty_Okc/pull/2

Idea is to have a Background monitor that watches for new people being loaded onto the matches page, so that we can strip unnecessary information out of their profiles - such as the text for "& Match" and the abbreviation of the state that they live in.

My first attempt was to use a Chrome extension background function to watch for Requests, but that didn't seem to work. This one brings in a library specifically built for monitoring changes. It is a little larger than I had originally wanted, but certainly does the trick. Not 100% sure if this should be merged, since it does dramatically increase the plugin side (though some of that could be remedied by actually minifying the other file.)

(EDIT: Even without minifying, the total package size goes from 30k to 43k, so it's not a huge bump, but it definitely adds a lot more complexity. With minifying, it goes to about 40k. Considering it adds both jQuery AND mutation-summary, that's really not bad.)
