Missing implementations in NSScanner class

[Mathias Bauer]

Hi,

I discovered that NSScanner misses some "scan..." methods. At least in 
one case it should be trivial to add it:

> - (BOOL) scanInteger: (NSInteger *)value
> {
>         long long result;
>         BOOL ret = [self scanLongLong:&result];
>         if (value && ret)
>                 *value = (NSInteger)result;
>         return ret;
> }

Would it be possible to add this as a patch?

Regards,
Mathias
