Commit 31. (Beta Candidate)
1) Important fix for 'minor' bug (typo) which prevented data-linking when
 window.name !== "" - e.g. in jsfiddle samples.
2) BREAKING change - but only if NOT using jQuery. See #191:
 With this change the JsRender API for with and without jQuery is now
 identical except that with jQuery, window.jQuery is the global namespace
 object, typically mapped to var $, and without jQuery, window.jsviews
 is the global namespace object. If in the second case window.jsviews is
 also mapped to var $, then the API for both scenarios now beccomes
 identical and allows a single documentation and samples set to be provided
 for both scenarios:
 $.views provides access to the full JsRender (and JsViews) APIs
 e.g. $.converters. But in addition, some important APIs ($.templates and
 $.render) are also made available directly from $...
3) The attr and url converters no longer convert null to "". This allows
 JsViews data-link="someTarget{attr:expression}" to remove the target
 attribute if the expression returns null, just as is the case already for
 data-link="someTarget{:expression}"
4) Modified sample "20_without-jquery.html" to show proposed pattern for
 mapping window.jsviews to var $, with API change above.
 "11_accessing-parent-data.html
5) Added example of accessing root data as ~root - within existing sample
