Bulk remove items from Steam Marketplace

devtools.js

// Push F12 when you're logged into steam in your browser, to open the devtools window
// Edit the window.appid line to change it to the app you want to remove all items from
// the marketplace for, and maxloops to the number of times it'll pull 100 and try to
// remove them. If you have lots of OTHER things in the market, this might not be for
// you, as it will only look at the first 100 items you have up for sale.
