Add Node Line/Column Generator

Fix Errors.hpp dependency on v2script/Parser.hpp
Add node location print to headless/main.cpp
Add Node::line_col << operator
Add Node::cast_to

WARNING: Takes advantage of non-standard behavior in unordered_multimap
	THIS IS A HACK FOR NOW
	Only GCC unordered_multimap::equal_range sees elements backwards
	Prefer moving off of unordered_multimap to something like EASTL hash_multimap
