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

Switched the 'pragma once' to only happen on MSVC, or gcc >= 3.4 (it was causing trouble on the sun compiler)

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

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

Renamed the valid/possible tokens to a single variable status with enums valid, invalid, and unverified.

Added stream input to the regular expressions, greatly simplifying the usage (in particular, we no longer have to specify the number of characters to be checked).

Wrote a simplified regular expression parser to make life easier (it only does single matches; i.e., no one-or-more matches, etc.).
Fixed some of the whitespace/line break matching.
