/***
* History:
*
* 0.2.2 Change made:
* - For the fix around the "Tax Free" checkbox of the "Edit Product
* History" dialog, a jQuery function call was failing so we're now
* using its DOM native equivalent.
* (2016-05-06)
* 0.2.1 Changes made:
* - Fixed the always-unchecked "Tax Free" checkbox for the dialog
* "Edit Product History".
* - Updated element id for the "Description" field of the dialog
* "Edit Product History".
* (2016-01-24)
* 0.2.0 Changes made:
* - Updated the "producthistory-template" template to match column
* names recently added by outofmilk.com, while at the same time
* disabling the CSS code previously used to display custom column
* headers.
* - Updated the "producthistory-template" template so that, like the
* original one, "Yes" & "No" are used as values for the "Tax Free?"
* column instead of "true" & "false".
* - Fixed the non-working "Tax Free" checkbox and empty "How Much?"
* dropdown list for dialog "shoppingeditpopup".
* - Fixed the URL used for the "icon-taxfree.png" image whenever
* adding or editing an item that is tax free.
* (2015-09-17)
* 0.1.7 Changes made:
* - Updated script for use with the repository [gf.qytechs.cn].
* - No change made to the code.
* (2015-09-14)
* 0.1.6 Changes made:
* - Kept being annoyed that everytime I added/changed a UPC from the
* product history it wouldn't update, so now I re-implement method
* saveProductHistory() (from "ProductManagement.js?v=...") with the
* added tweaks (after all, I'm the one adding the column). Also,
* updated the producthistory template with a new class for that
* column.
* NOTE: I'll have to watch out for any updates/changes to the site
* as I replace the whole function, since obviously I cannot
* just patch the existing code. Oh, wait...
* NODO: I know they say "eval() is evil()", but what if I'd say the
* words "toString()", "String.replace()" and "eval()" in that
* particular order... OK, I'll leave that hanging in the air.
* - Took the opportunity to fix the call that sets the initial width
* of the "Product History Management" dialog, which was failing with
* errors of the sort "Permission denied to access property".
* (2015-06-30)
* 0.1.5 Change made:
* - Added outofmilk.com as a possible domain for include URLs.
* (2015-04-02)
* 0.1.4 Changes made:
* - Changed how the initial width of the "Product History Management"
* dialog is set.
* - Implemented changes to add a "UPC" column to the product history
* table (by changing its jQuery UI dialog template; this is possible
* since the web service's "GetAllProductHistoryItems" method already
* returns the stored UPC value for each history item).
* - Removed keep-alive code since no longer necessary.
* (2013-08-19)
* 0.1.3 Changes made:
* - Removed "!important" when setting the (initial) width property of
* the "Product History Management" dialog (since the specified width
* isn't meant to be permanent).
* (2013-04-05)
* 0.1.2 Changes made:
* - Added javascript code to keep the session alive (without the
* need to refresh the page).
* (2013-04-04)
* 0.1.1 Changes made:
* - Added column names for dialog "Product History Management".
* - Changed text alignment for (newly-named) column "Tax Exempt".
* (2013-04-04)
* 0.1.0 First implementation. (2013-04-02)
*
