dev cmd improve initial startup time

[GuyARoss]

Startup times for the initial iteration of the application can take 3-5 seconds on my machine. This is primarily due to the fact that the application bundles all web wraps upon initial load.

This can be prevented by creating a "placeholder" static document in the place of all bundled applications. Orbit currently supports bundling on webpage redirection, so as the page redirects orbit will apply the initial bundle.
