Fixed Issue #3- "Provide some Guidance About How to Use Edge Inspect"

Adding an extension "how-to" dialog to provide the user with first-run instructions on how to use Edge Inspect.  Implementation based on the EWF extension's implementation of a similar "how-to" dialog.  Similar to EWF, this dialog will appear the first time you click on the Inspect toolbar icon.

From the Inspect extension's UI, you can also view the same dialog using the menu item "Getting started..." in the dropdown that you get from clicking on the "Edge Inspect CC" caption.

The content comes from the Edge Inspect "Getting Started Guide" that displays on first-run in their Chrome Extension.  I altered some of the content to match our implementation within Edge Code.
