Add EmitterStyle, which will allow sequence or map style (i.e., flow or block) to be preserved between parsing and emitting

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

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.

Switched to reading the entire file into a buffer at the start.\nThis speeds it up a TON (like 100x).

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.

Moved the input stream, together with line/column info, into its own class, which allowed some other stuff just to pass the stream, and not have to be a member of Scanner.
