Adding the create flow for Project Board (Workphlow) columns.

Summary: This adds in the create flow for the Project board columns on the super secret board page which totally doesn't do anything right now.

Test Plan:
1. Apply diff.
2. Go to super secret page.
3. Click link close to top with a way too long name.
4. Enter a name for the column.
5. Enjoy a new column briefly before realising you cannot remove it.
6. Stay happy!
