Fixed several bugs in Campbell2003SHARE and ToroEtAl2002SHARE:
- corrected AFrock factors
- corrected reversal of normal and reverse style-of-faulting terms
- corrected computation of standard deviation

Still to do:
- correct Frss factors for periods between PGA and 0.1 s
Added adjusted forms of Campbell2003 and ToroEtAl2002 GMPE's.
So far, only vs30=800 m/s and kappa=0.03 s is implemented.
Added .BAT file to compile speedups on Windows.
