MAJOR CHANGES

Got rid of rushee table, using wp_users and wp_usersmeta instead.
Added all support for that.  Changed most occurrences of rushee to pnm.
 Still needs some cosmetic work.
Moved entry points, partially fixed reports

Moved short code entry points to the top of files, added check for
logged in users.  that will be refined later to check for specific
kinds of users (i.e. rush chairs, admins, and pnms)
Added query to get pnm by netID.  Since the eventreg table stores the
netID (and not the name) I added queries to get the name out of
wp_usermeta.
