MikMod working under Win32

[Corona688]

I put a clause in mod.c that makes it assume a 44Khz samplerate if the
requested samplerate is zero.
I replaced
md_mixfreq = sample->desired.rate;
with

if(sample->desired.rate==0)
     md_mixfreq=44100;
else
     md_mixfreq = sample->desired.rate;

and now MikMod works. =)  I'm happy.
