2aa41c82da Modify the SQLITE_DBCONFIG_ENABLE_TRIGGER setting so that it only disables 
main-schema triggers and allows TEMP trigger to continue operating.  This is
safe, since only the application (not an attacker) can add TEMP triggers.
It will also all us to disengage SQLITE_DBCONFIG_ENABLE_TRIGGER on Fossil
databases since Fossil has no main-schema triggers but does use TEMP triggers.
