New Dojo Vdom Rendering Engine

[agubler]

Enhancement

The existing vdom implementation is becoming difficult to maintain, enhance and performance tune due to starting with maquette's vdom and integrating dojo's widget concepts into the existing code base. To enable dojo to continue enhancing the core renderer's functionality and flexibility, a ground up re-design is required. The re-design will provide a backwards compatible solution that ensures both widgets and virtual dom nodes are equal citizens within the engine and enable enhancements such as scheduling to be addressed.
