• added to SPArrayAdditions.h: NSArrayObjectAtIndex() inline function

- id o = NSArrayObjectAtIndex(anArray, index) :== id o = [anArray objectAtIndex:index]
- this speed up it ~3µs per call 
- replaced that inline function for such calls within loops to speed up them
• used IMP function pointers for keepAlive calls within queryString:
• set -O3 (Fastest) compiler option 
• allow in preference pane "Tables" to set the Limit up to 50000
