Moved error-handling to a separate class - Diagnostics. We were earlier returning errors as tokens which did not work very well when error occured while parsing a preprocessor directive. Now all returned tokens are valid. Errors are reported via an abstract Diagnostics interface. Updated unit-tests with the new scheme.

Reafactored Lexer class to allow chaining. The full chain when parsing #if directive looks like this: Preprocessor -> MacroExpander -> DirectiveHandler -> MacroExpander -> DefinedFilter -> Tokenizer. This chain dynamically changes depending on the current context.
Also added an incomplete implementation of #if handling and ExpressionParser to illustrate how this design is supposed to work.

Do not return newline and number sign. They are for internal purposes only.
