// @description After completing a HIT anywhere within your queue (i.e. HITs Assigned To You), this script will automatically continue the HIT at the top of your queue. 
// For example, if you sort your queue by Time Left (least first), you can use this script to work on the HITs that are closest to expiring instead of mturk's default behavior ignoring what your queue is sorted by and putting the oldest HIT next in line. You should only need to set the sort order once. HITs accepted after setting the sort order will be sorted automatically by mturk. Additionally you can manually continue the HIT at the top of your queue if you visit "https://www.mturk.com/mturk/myhits?first". Create a bookmark on your toolbar to quickly jump to the first HIT in your queue. This is especially useful if you just caught a HIT that will expire quickly.

/*
 * Mechanical Turk has two types of HITs. By far the ExternalQuestion HITs are 
 * the most common. These HITs use an iframe to display the task, disable the 
 * yellow Submit HIT button, and use the hidden link with the id hitExternalNextLink
 * to direct the browser to a new page after the task has been submitted in the
 * iframe. The second type of HIT is the QuestionForm HIT. These HITs do not use
 * an iframe, use the yellow Submit HIT button to submit, and do not use
 * hitExternalNextLink to direct the browser to a new page.
 *
 * For ExternalQuestion HITs, fixing the queue order is as simple as replacing
 * hitExternalNextLink with the URL of the next link you wish to work on.
 *
 * QuestionForm HITs don't use the hitExternalNextLink, however we can utilize
 * the fact that after a QuestionForm HIT is submitted the URL ends with 
 * /mturk/submit to redirect the browser to the top of the queue.
