Quicker UpWork Search troch rimutaka

This extension greys out upwork.com job posts you looked at earlier to help you scroll through the list of UpWork jobs faster:

* new jobs - keep their original white background
* viewed jobs - greyed-out

This feature works only on search pages starting with https://www.upwork.com/nx/find-work/ and https://www.upwork.com/nx/search/jobs/. Only 1000 recent jobs are remembered.
