Refactorizations optimizing std::string usage:

Added to config.h to ensure that it is available everywhere
2) Added overloads for TestFixture::assertEquals for the most common use cases:

Ticket #5868 : Ignore variables called like a typedef when substituting typedefs

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)
