Hidden Special Classes Make for Good Single Class Racing

While testing some AI changes I noticed some CAR file classes were not represented in the Specials category when selecting cars. So, I looked at all the classes in every CAR file and added the class tags I could find as selectable in the Specials category in-game:

G2's 2003
G2's 2004
NG3's 2003
NG3's 2004
SP2's 2004
GT3 Cup

Edit GameData\SIM_Specials.gdb and add them in like this (without the blank lines):

SpecialClasses
{
GT_2003 = GT's 2003
GT_2004 = GT's 2004
NG_2003 = NGT's 2003
NG_2004 = NGT's 2004

G2_2003 = G2 2003
G2_2004 = G2 2004
NG3_2003 = NG3 2003
NG3_2004 = NG3 2004
SP2_2004 = SP2 2004
GT3CUP AND: 2003 = GT3 Cup 2003
GT3CUP AND: 2004 = GT3 Cup 2004
24H_2003 = 24H of Spa 2003
24H_2004 = 24H of Spa 2004

BMW = Bavarians
ITALIAN = Italian Passion
FERRARI = The Prancing Horse
AM = American Muscle
PORSCHE = Porsche Posse
BB = British Beef
}
