Item8375: plugin overloads the global JS object, breaking other plugins

This plugin overloads the global JS object (with json.js), which is bad practice and causes issues with other extensions that use JavaScript.

See Item2345 (DpSyntaxHighlighterPlugin) and Support.Question340 (EditChapterPlugin).

If it only uses json.js to parse JSON, then it could use JQuery instead.

ToolTipPlugin doesn't work with this plugin either. Given the number of bad interactions caused by this plugin, it's unusable in our installation.

Disabling JSPopupPlugin eliminated several problems on an installation of Foswiki 1.0.9 including:

• ImageGalleryPlugin's lightbox frontend did not work (clicking on a thumbnail loaded the image instead of a lightbox overlay).
• Using JQuery's .attr('disabled', 'disabled') on a set of form inputs threw an error (in firebug).
• Submitting a form asynchronously via jQuery Form Plugin threw an "uncaught exception" at location "JS frame :: http://wiki/pub/System/JSPopupPlugin/json.js :: anonymous :: line 72" (reported by firebug).
