The project fails to be built at Linux

[makaleks]

The project failed to be built at Linux. Here I attach the diff I had to apply to make the project working. The main problems:

• windows-specific conio.h is uncompetible and, furthermore, unneeded
• 0 is incompatible with std::ios::goodbit in linux implementation of std (glibc)
• sfml-main is not found on linux. That's strange, that sfml didn't form the library as an universal wrapper, so we have to wrap it ourselves

The other problem is that localtime_s is Optional to be implemented, and at linux it isn't. Moreover, it's interface at standard is different from Microsoft's implementation.
