Changed 'version' column from TINYINT to SMALLINT

- Tables are 'alf_prop_root' and 'alf_audit_app'
 - Added property test to update past the SMALLINT rollover to test reversion to 0
 - To modify your tables (not absolutely necessary)
   alter table alf_audit_app modify version SMALLINT NOT NULL;
   alter table alf_prop_root modify version SMALLINT NOT NULL;
