QDateTime: avoid relocations 

The short month names all have length 3, so store them in a multi-
dimensional const char array instead of as a pointer table.

Effects on Linux GCC 4.9 stripped release builds:
 text   -196B
 data    -64B
 relocs  -12 (est., somehow relinfo.pl reports nonsense on QtCore)
