Updated the CMake globbing so it only compiles sources starting with a lowercase letter (apparently Mac OS auto-generates files looking like ._whatever and it was trying to compile those too)

Modified old gcc version patch so it still uses the new Node::Read in Visual Studio. Also broke up the \uNNNN characters in the spec tests into \xNN-type strings.

(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)

Fixed bug in anchors with no content. This involved refactoring the 'implicit sequence' concept (where a map and a sequence start on the same indent, but we read the sequence as more indented since the '-' is visually an indent).

Switched from loading test files to testing specific parsing constructs. The tests don't fully cover the span (eventually I'll add more, maybe), but there's a bunch there.
More to the point, the yaml-reader program doesn't do any file IO, so it doesn't require a specific working directory.
