update_6001 has invalid use of db_add_field

I just ran the update from a 5.x install to 6.x and found the 6001 update does not add the set_active_menu column correctly...

The fix is to change

db_add_field($ret, 'custom_breadcrumb', 'set_active_menu', 'int', array('default' => 1, 'NOT NULL' => TRUE));

to

db_add_field($ret, 'custom_breadcrumb', 'set_active_menu', array('type' => 'int', 'default' => 1, 'not null' => TRUE));
