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.

CheckBufferOverrun::checkFunctionParameter alreacy considered usage of a

With the patch the same is done for switch statements.
