Phase 2 Items:
1) Update copy of registration email to volunteer, and cc coordinator.
2) Add Step 6 to wizard.
3) Implemented County Public Training: add Training to the volunteer and site exports, fix warnings on training-add form.  Admins can set up the link-and-learn and county public trainings.
4) Can add and edit Trainings as a coordinator.  View page looks OK now too.
5) Create separate volunteer landing page at /dashboard rather than displaying the tax site listing.
6) PDF pages 2-4, with caveats listed in spec.  Changes as per Volunteer Registration Content PDF page 1.
