  16.  * History:
  17.  *
  18.  * 0.2.1  Changes made:
  19.  *        - Fixed the always-unchecked "Tax Free" checkbox for the dialog
  20.  *          "Edit Product History" dialog.
  21.  *        - Updated element id for the "Description" field of the dialog
  22.  *          "Edit Product History" dialog.
  23.  *        (2016-01-24)
  24.  * 0.2.0  Changes made:
  25.  *        - Updated the "producthistory-template" template to match column
  26.  *          names recently added by outofmilk.com, while at the same time
  27.  *          disabling the CSS code previously used to display custom column
  28.  *          headers.
  29.  *        - Updated the "producthistory-template" template so that, like the
  30.  *          original one, "Yes" & "No" are used as values for the "Tax Free?"
  31.  *          column instead of "true" & "false".
  32.  *        - Fixed the non-working "Tax Free" checkbox and empty "How Much?"
  33.  *          dropdown list for dialog "shoppingeditpopup".
  34.  *        - Fixed the URL used for the "icon-taxfree.png" image whenever
  35.  *          adding or editing an item that is tax free.
  36.  *        (2015-09-17)
  37.  * 0.1.7  Changes made:
  38.  *        - Updated script for use with the repository [greasyfork.org].
  39.  *        - No change made to the code.
  40.  *        (2015-09-14)
  41.  * 0.1.6  Changes made:
  42.  *        - Kept being annoyed that everytime I added/changed a UPC from the
  43.  *          product history it wouldn't update, so now I re-implement method
  44.  *          saveProductHistory() (from "ProductManagement.js?v=...") with the
  45.  *          added tweaks (after all, I'm the one adding the column). Also,
  46.  *          updated the producthistory template with a new class for that
  47.  *          column.
  48.  *          NOTE: I'll have to watch out for any updates/changes to the site
  49.  *                as I replace the whole function, since obviously I cannot
  50.  *                just patch the existing code. Oh, wait...
  51.  *          NODO: I know they say "eval() is evil()", but what if I'd say the
  52.  *                words "toString()", "String.replace()" and "eval()" in that
  53.  *                particular order... OK, I'll leave that hanging in the air.
  54.  *        - Took the opportunity to fix the call that sets the initial width
  55.  *          of the "Product History Management" dialog, which was failing with
  56.  *          errors of the sort "Permission denied to access property".
  57.  *        (2015-06-30)
  58.  * 0.1.5  Change made:
  59.  *        - Added outofmilk.com as a possible domain for include URLs.
  60.  *        (2015-04-02)
  61.  * 0.1.4  Changes made:
  62.  *        - Changed how the initial width of the "Product History Management"
  63.  *          dialog is set.
  64.  *        - Implemented changes to add a "UPC" column to the product history
  65.  *          table (by changing its jQuery UI dialog template; this is possible
  66.  *          since the web service's "GetAllProductHistoryItems" method already
  67.  *          returns the stored UPC value for each history item).
  68.  *        - Removed keep-alive code since no longer necessary.
  69.  *        (2013-08-19)
  70.  * 0.1.3  Changes made:
  71.  *        - Removed "!important" when setting the (initial) width property of
  72.  *          the "Product History Management" dialog (since the specified width
  73.  *          isn't meant to be permanent).
  74.  *        (2013-04-05)
  75.  * 0.1.2  Changes made:
  76.  *        - Added javascript code to keep the session alive (without the
  77.  *          need to refresh the page).
  78.  *        (2013-04-04)
  79.  * 0.1.1  Changes made:
  80.  *        - Added column names for dialog "Product History Management".
  81.  *        - Changed text alignment for (newly-named) column "Tax Exempt".
  82.  *        (2013-04-04)
  83.  * 0.1.0  First implementation. (2013-04-02)
