Prepare quickstart startup hooks for new UI interface

[seamustuohy]

Reconstruct the back-end of quickstart so that when the final UI review is complete the new version of quickstart (which should be renamed) is seamlessly presented upon a routers first startup as well as as the basic menu. This will consist of the following:

• Create a temporary entry that captures the front page on first boot
• Create hooks that reset the front page upon completing quickstart or clicking exit/advanced
• Version 01 UI review is a prerequisite to this task. Remove all configuration from "quickstart" repo and push to custom menu repo, so that only startup specific tasks like these remain.
