Test Case 4 - Grad Students, Fall Only Award

Added P_UPDATE_FUND_AMT_RULE() which updates the G_AWRD.AMT - divides it
by 2 -  (before any other logic) if the student is a fall graduate.
RPRAWRD will not create a Spring RPRATRM record for fall graduates and
this is what I had to do to get this to work correctly.
