win32gui: prevent male valkyrie (from <Someone>)

>Steps to reproduce problem:
>1) make sure you don't have race, role, gender specified in your
>   defaults.h, then add
>   OPTIONS=role:Valkyrie,race:Human,gender:male,align:lawful
>2) start a new nethackw.exe game
>3) Uncheck "Random" from gender box, now you can select from male
>   or female, not only female.
>4) Select male and click OK.
>5) When game begins press shift+O (Options) and look to gender.
>   Your valkyrie is male.

defaults.nh values were not used the dialog initialization. That's
why both male/female options were available for Valkyries. This is
now fixed.

Also added: checking for consistency of the initial settings and
resetting all incompatible values to ROLE_NONE.
