Disabled several checks and simplifications for C code, if they are C++-only. Do not match arguments for C code, since there can't be overloads.

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.

Cache results for TokenList::isC() and TokenList::isCPP() to avoid redundant calls to Path::isCPP()/isC(), which perform slow string operations (conversion to lowercase, substring, comparisons)

Replaced static variable isCPP in Token (was not threadsafe):
...
- Encapsulate parameters passed through AST compiler functions in a struct
-> Reduces maintenance overhead when changing them
-> Contains parameter indicating if the file is C or C++
- Added eKeyword Token type (at the moment, only true for C++ keyword "delete", but should be set for other keywords as well)
