/** This simple script makes the page titles more useful. Most pages on Mechanical Turk simply have
    "Amazon Mechanical Turk" for the title and if you have multiple tabs open, it can be hard
    to determine which is which at a glance. This script puts an appropriate title for nearly
    every page on AMT.
