Change Report Preview into Build Report tab

[AARON-CLARK]

Closes #348.

The thinking here is the report preview tab is not just for visualizing the report, but it's also for configuring and capturing other important information that orgs may want to keep track of (in one place - the app). This solution offers a long form "summary" section where users can fill it up with whatever content they want. Not just content about riskmetric metrics. "Overall Comment" is still nice to have, but it is intended to be short hand.

Currently, this PR is a work-in-progress but includes a fully functional "module" to allowing the creation of "pkg_summary" comments in the db (abbreviation = "s"). If you test, you will see that "Submit" and "edit" buttons appear and disappear as needed. Also, once submitted, the text box is disabled until "Edit" is clicked. Below, you can see that I made the Report contain headers just like the HTML report, and put a shaded box and border around the div so that it really pops and looks like a page.

TODO:

• Add pkg summary to the reports
• Introduce markdown editor into Build Report tab this is on hold
• Define report download configs so users are empowered to include what's important to them
  • Impact report preview - this is trickier than I thought
  • Impact reports
• Make sure those configs are shared globally so the both download handlers use them by default

Would love to think of a way to create a reporting template that others can use

FYI - I wanted to implement a markdown editor instead of a boring textAreaInput() (like shinymarkdown) to produce something github-like the editor seen below, but alas - the package doesn't seem to work well with shiny modules. I opened an issue but we should probably use something that's on CRAN anyway.
