Mojo JS Bindings: add show_image example

Mojo JS Bindings: add show_image example

Add a simple example based on the window and view managers.

The skydb app can now handle apps that want to embed another view.

Corrected a problem in unique module name generation. An otherwise unique module name could be shadowed by a parameter name (service_provider in ViewManagerService Embed). Appended a "$" suffix to module names to avoid the collision.

This patch includes the debugger.cc fix we talked about. Other than that, it's
just a simple JS demo.
