Add 'show_all', 'hide_all' methods on top level renderjson element

[movitto]

When called, these will walk down the renderjson DOM structure and invoke 'show' and 'hide' on all the appropriate elements.

Use like so:

const rj = renderjson({ js : 'on })
document.getElementById("test").appendChild(rj);

rj.show_all();
rj.hide_all();
// ^ wire these up to a button click, etc

This is an interesting function, and use case. But not all json object graphs are tree. We explicitly, turn the tree back into a graph (for complex DTO object graphs and json schema), before rendering them.

But there may be other graphs passed to this renderer, you can make it impervious to such infinite recursion by adding a array|stack parameter and checking that the object hasn't been seen yet before descending. Besure to put before descending and pop after returning.
