Guarantee project gets set up properly

You can go through the walkthrough in a haphazard manner, and wind up with a project that is not initialized yet. Also, at any point in time you can cancel the project initialization process.

• [x] We need to give UI feedback to the user about incomplete project setup.
• [x] We need to ensure that the user completes the walkthrough before interacting with files in an uninitialized project.
• [x] We need to update the project management webview with a 'checklist' that checks for project setup status for each step; this should be incorporated with a project overview and integrity check
• [ ] We need to take an inventory of what is needed for a completely initialized project
• [ ] Project manager should open a notification with buttons to jump to the project manager view

DoD

• [x] User is fully informed about whether they have a complete or incomplete project (refs #4 )
• [ ] User can proceed to use the project in an obvious and intuitive manner
• [ ] User is presented with project overview on startup IF the project is incomplete
  • [ ] On extension activation, we check health of project
  • [ ] If project is in any way compromised or incomplete, we activate the project management view

Initially, @sampjvv set this up to check whether someone has gone through the walkthrough steps. However, in testing I found it can sometimes mistakenly think the project is not set up, so I modified the code to check for the presence of key project data rather than checking whether someone followed the prescribed process to get to the present project state.

I've modified the project overview to indicate missing fields in the project setup.
