Refactorizations optimizing std::string usage:
...
1) Added global static const std::string emptyString; object:
-> Replaces some static variables in functions which might be not threadsafe
-> Avoids constructor call (std::string::string(""))
-> Even functions that return an empty string in some branches can return by reference now.
Added to config.h to ensure that it is available everywhere
2) Added overloads for TestFixture::assertEquals for the most common use cases:
-> Moves conversion from const char[] to std::string into a function, reducing code duplication in binary.

Add a new test for OpenFile function from windows.cfg.
...
It is here as a reminder for a TODO. When used with OF_EXIST flag, the function OpenFile doesn't return a handle and thus, doesn't leak any resource.
As cppcheck doesn't support such feature yet, it's added a TODO not to be forgotten for later fix when cppcheck supports this.
Also added a naive check, just to ensure the OpenFile check doesn't get broken when adding support for OF_EXIST.
