Flipped the include guard and the pragma, and don't use the pragma for early versions of gcc (< 3.4)

Fixed leak when adding duplicate keys (and actually changed the behavior - now we take the first instance, not the last)

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)

Added emitting for a YAML::Node (instead of the ad-hoc std::ostream overload) so it'll actually emit valid YAML always

In particular:
1. Windows CR/LF weren't read properly (issue #11)
2. Scanning wasn't reading EOF properly
3. Documents may be empty (this was old, I think)
Also fixed some VS2008 warnings on /W4.

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

Fixed a bug in the last newline of a block folded scalar.

Specialized the overloaded [] operator for int/unsigned, and added a size() function, so that you can iterate through a sequence node like a vector.

Fixed a silly bug in the simple key pushing (queues are FIFO!).
