Updated how NanoUI renders templates, using JSRender without the JSViews data-linking. This makes it much easier to create NanoUIs
as you don't need to provide the full data structure up-front, part of an effort to make NanoUI more accessible.

I have removed the carets (^) from all templates as they are not used any more.

For safety I moved the src_object and user checks from the master controller to the nanoui process proc.
