Update version to 1.0.4

* Problem: in MSVC++ UNICODE builds, the _tcsncmp and _tcsicmp defined via <tchar.h> need wchar_t* input, but that's not what we have available here

Solution:
1) in place of _tcsncmp, just use strncmp, which ought to be standard: http://www.cplusplus.com/reference/cstring/strncmp/
2) in place of _tcsicmp, call strcasecmp, and in MSVC++ builds create a wrapper that actually calls _stricmp (and never _wcsicmp)

* #include <string.h> and not <strings.h>
