Added looseList() method to linkList

Sometimes someone else wants to take over a linkList's list of nodes. When and if this is the case, calling looseList() will make the linList object set its list pointer to NULL effectivly cutting ties to its list of nodes. Very handy for sorting and shuffleling nodes using two linkList objects.
