Added explicit doc start/end tokens for the emitter, and set it so that if you try to write after you've already written a full doc, it writes a doc start and continues

Refactored bool emitting to make it 1) correct for the short bool form and 2) not barf on early versions of VS

Moved all the includes to a subfolder yaml-cpp so they don't interfere with other libraries' includes

Refactored emitter operator << overloads to not template them, so it's easier to overload for pointer types

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.

Added CMake scripts for other platforms\nFixed some bugs that gcc complained about\nFixed CR/LF vs LF bug

We were getting memory leaks (as told by the CRT detectors, which I also added), and there's really no reason (as long as we're careful) to use pointers there.
