Add Ability to Resubmit a Boundary

[rajadain]

Overview

Once an application has been put in "Needs Revisions" as of #160, the contributor needs to respond to the requested revisions. The contributor should be able to view the main feedback / note, and the annotations (if any). The contributor should be able to modify the boundary, and submit it again.

• When the boundary is in Needs Revisions, have the "navigate to draw page" button in the Boundary Details map say "Revise Map"
  
• Clicking the button should create a new submission in the database attached to this boundary, with the contributor as the creator, and the current shape as the default, but not submitted_at, so it will re-enter the draft state
• Once this is done, the user should be navigated to the draw page, where they can make edits
• They should be able to see annotations, but not edit them:
  
• The annotation pop-up should not have a "Save" button, and the text should be darker than the current gray to make it easier to read:
  
• Clicking "Review and submit" should open another submission form, just as before, and the workflow should be the same as submitting a boundary for the first time
