Two databases, very close to AHA's supplied databases
added !==FALSE check in form save, since wpdb->update returns 0 on no data
updated, FALSE on not-updatable data;
in cc_aha_update_form added drop false, empty and null $_POST values. If
nothing selected, don't clear val in db;
updated input render helper functions to include DIST_ID...will have to
roll this out to all page inputs as well
added columns to the school/board tables for new input numbers we created - not sure if
comprehensive at this time;
updated survery template tags to reflect/force new school $_POST array
structure;
find and replace on values on the pages for DIST_ID and DIST_NAME, so as
to change thier db as little as possible;
added more sane comments to database getters/setters
whoops - setup empty array, not function
