compilation bug fix for bsds

[Yarin]

Hello,

Your code fails to compile on some BSDs out of the box. The fix is simple, but I thought it would be nice if you would commit the fix to your code to get it working out of the box for more people.

---------------------------------------------------------------------

Open ./MaraDns.h:
On what should be line 30 which says "#include <stdint.h>", prepend:

#include <sys/types.h>
#include <sys/time.h>

Open ./server/udpsuccess.c, and prepend the same 2 lines before all code (but not comments).

---------------------------------------------------------------------

Great software, BTW :-)
