Replace uses of atoi() with strtol() or stroul() as appropriate (#394)

Browse Source 
As a side-effect of this change, we also resolve a a problem with
signed file version numbers, so that instead of version 2147483647
wrapping to -2147483648 we can go as far as 4294967296 before we
have issues.  Various sprintf() formats get changed from %d to %u.
The DOS version code is left behind as int versions.
