More performance work - huge improvement in dictionary lookup and
perhaps 15 percent improvement elsewhere.
* src/NSString.m: ([-hash]) changed hash generation to produce a
more evenly distributed value so that dictionary lookup works
better for large dictionaries full of similar keys.
* src/NSDictionary.m: ([+dictionaryWithObjectsAndKeys:,...]) fixed
memory leak.
* src/include/NSGDictionary.h: Removed - not needed.
* src/NSGDictionary.m.old: Backup added.
* src/NSGDictionary.m: Complete rewrite.
* src/FastMap.x: New map table stuff for NSGDictionary.
