// Of these, only name, id and bookURL are mandatory (but hostname, getISBN, ajaxURL and ajaxPrice are usually needed too).
// name: book store name listed in infoline window
// id: a short unique id string for all document nodes related to this book store
// hostname: a hostname regexp used to determine whether to look for ISBNs on this page
// bookURL: address to link the name to, %s being replaced with the ISBN of the book
// getISBN: function run on book store pages to find the book ISBN it's about; returns false (no book), or an ISBN string
// -- or -- regexp applied to the full URL of the page, whose first matched paren pair gives the ISBN of the book shown
// -- defaults to /isbn[\/=]([0-9X]{10})(&|\?|\.|$)/i if omitted
// ajaxURL: address to pick up price for the book whose ISBN is %s, for ajax handler (defaults to bookURL, if not given)
// ajaxData: '' by default; if given, the data to provide with the ajax request body, %s replaced with the ISBN of the book
// ajaxMethod: POST by default (if not given); which HTTP method to access the above
// ajaxHeaders: HTTP headers for the AJAX request. Adds a Content-Type: 'application/x-www-form-urlencoded' header for all
// POST requests missing a content-type declaration.
// ajaxPrice: function run on fetched AJAX page to get book price; returns false (not found) or a price and currency string
// or an associative array from store id to price and currency string, when one AJAX request can get many prices
// -- or -- regexp (or string form, the latter mostly useful avoid quoting /:s) whose first paren picks up the book price
// -- or -- false, in which case no xmlHTTPRequest is ever made (for instance because some other handler finds the price)
// priceFix: if ajaxPrice was a string and this function is provided, the resulting price is fed through the callback
// updateURL: if provided, a function run on the fetched AJAX page, to get a new (or proper) URL for the book link
