Completely overhaul how we do sorting in -base. GSSorting.h now defines an

Browse source 
interface that can be used for all sorting tasks in the library. The actual sort
algorithms to use are now plugable. Timsort is the new default sorting
algorithm, the existing algorithms, shellsort and quicksort, can still be
selected using a configure switch.

Also implement the new NSComparator (blocks) based sorting and insertion index
searching methods for NSMutableArray and NSArray.
