Add har inspector for pages

[g00dnatur3]

Adding a new "PageReporter" to help users debug and find pages that have failed requests

The PageReporter will log request and response information to the stdout

Below is a screenshot of how this information will look when displayed on screen.

please keep in mind the screenshot is of a SUCCESSFUL request/response...

only to show what it looks like...

the actual code itself will filter out the success and only show the errored

unit test are being worked on,

please review the overall design -- and provide any feedback

thank you &
Cheers
