Query stripper

Strips annoying query parameters from URLs. It does utm_* (google), atl_* (atlassian) and ref_ (imdb) out of the box. More unwanted tokens/params are configurable on the Options page.

This happens BEFORE page load, so the query params WON'T be sent to the server and your URL is clean for copying.

-It also cleans up the URL after it's changed via History API.- (Not anymore, temporarily.)
