Changes from 9/3/13:
1) Allow volunteers to search for tax sites by the day of the week they're open
2) Fix export of "tax years processed" or "types of returns" if multiples are selected.
3) Prevent the selection of multiple roles by using the Back button in the wizard.  Also ensure that any existing tax-search results are wiped out prior to rendering that screen if you go back and forth.
4) Only display the training type on the view-training page, if it's the owner
8) Allow coordinators to change the county of a listing (i.e., do not honor "locks").
9.1) Prevent the Closing Date from being prior to the Opening Date
