This has to be done explicitly for Windows and I think doesn't hurt for Linux.
It doesn't find the dependencies on Win, may be because we're still building
STATIC there, tho I'm not sure if DLLs wouldn't have this problem, either.

* reset_values function to set all Values to their defaul-construct state
* read-only access to all variables of some type via get_all<T>
* Variables cloning
* convenience functions: get_or_throw, get_value
Value subtypes now contain a value_type typedef and require a const value_type& get_value() const member function.

use a stringstream in parse any, gather all exceptions so more useful info is displayed in case all rules fail

This is how they do it on the web, really. It works as expected and matches any flavor of newline (Win, Unix, Mac) despite the ambiguity that "\n\r" can be matched by two subrules, in the end it will be properly matched just by one rule. Also, grammar can be k=2 for lexer.

BRING BACK THE Q_MARK!!!! campaign ;) Fix the ?? instead of just blatantly deleting it, and we can decide later whether we really want to remove it.
