Removes autocomplete="off" attributes
// WHAT IT DOES:
// Sites can direct the browser not to save some password fields (for
// increased security). They do it by tagging the password field with
// autocomplete="off", in the HTML. "Allow Password Remembering" removes
// these tags, so that the user can decide which password the browser
// should save.
