Handled the case where int and float are of correct format, but large. The GLSL spec is not very clear on how integers should be interpreted for expressions. C99 says the expression is of type intmax_t. I am parsing all integers as int except those in expressions, which are being parsed as unsigned int.

Replaced pp::Token::value with pp::Token::text. The term value will be used for a function which will convert text to integer/float constant.

Introduced preprocessing token types. This fixes a bug where invalid tokens inside excluded conditional block may report diagnostics. Now we let the invalid tokens to bubble through the preprocessor so that they have chance to be skipped.

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.
