(Actually) fixed the folding newline bug, but it's a bit messy, and we don't accurately make the distinction between block folding and flow folding

Added spec tests (minus tags, directives, and BOM) up through example 5.12 - this exposed an error in line folding

Refactored the operator >> and Node::Read default functions, as well as the conversion functions, to more easily read new types as keys (this uncovered an error, in example 2.11 of the spec)

Added templated casting to nodes, as well as operator == and != (for quick checks, especially to help in testing). Implemented size() on a map node to return the number of key/value pairs (as in std::map)
