Solidity Scan usability

[ryestew]

From our UX discussion:

• Is the button for opening SolidityScan in the right place in a users workflow - inside the deployed instance?
• After the continue button is hit, nothing happens for some time. A modal should open with a spinner.

And not in our UX discussion - if the user does the scan and then close the report, to view the same report again,they need to rerun the scan. I'm not sure if we can save the scan or if that is really needed - but I sort of expected it wouldn't disappear.
