minor tweaks to code

remove cursor : move from css and prevent double adds on IE9

We've hit a FF-specific Dojo bug, detailed here
http://bugs.dojotoolkit.org/ticket/14491
Added temporary work-around.

Also, added dijit theme files for the page widgets.

I have updates to index.html and todo.css to have the checkbox work with the staetful model, and to use a dijit/InlineEditBox for the todo, Let me know what you think.

Initial setup of Dojo 1.7, using DojoX MVC to bind between a stateful
model and UI elements. Use dojox.mvc.Repeat to render model items as
a series of list items.

ExtJS 4 Todo addition

jQuery example - added count on Clear button

Also some selector caching and other small optimizations.

Adding jQuery-only todo example. This will be more clearly made available in TodoMVC 0.3 along with the other new examples coming soon.
