Support another gender that M/F

I want to support another not binary gender instead of M or F only.

I can change prompt string message "put you gender/sex (M/F)" to "put you gender/sex (M/F/L/G/B/T/X)" at text.dat

I see that ;uedit can put any others characters than M/F also console uedit tool just work. But at new user prompt, these answer seems to be limited for M and F characters only

Scfg must be update too.

Thanks!!
