Switched the utf bom checking to putback in the stream (instead of keeping a secondary buffer), which fixes a bug when there's only one ascii character

Split the yaml.h file into new/old API, which we'll then copy to yaml.h at build time (so the right one gets installed)

Set the default build to the old API, and removed the duplicate spec test implementation for the old api

Switched Node::operator=(const Node&) to *not* force itself to create its node first (since we're just assigning them)

Switched the node_ref to *always* create its data (since now the Node itself doesn't always create itself)

Set the pimpl node in Node to be optional, so we don't create unnecessary guys every time you call Node tmp = foo[value];

Fixed new API node key/value insertion in NodeBuilder (it was using the wrong condition on when it had added a key already)
