json-cpp Code

added dependency

Stripped carriage return and added eol-style native prop.

Updated platform on linux-gcc to include compiler version (necessary for multiple targets built in same directory, and not a bad idea for other builds).

Without this file, scons must be run twice initially. Hopefully, the file gets rebuilt properly, as I do not know how to fix the scons rule correctly.

LD_LIBRARY_PATH needed for linux build tests. (Really, passing -Wl,-rpath to the linker would be better, but scons is not good about automating that.)

Added svn:eol-style native

I always have compiler problems when using operator when I pass int instead, so I added a note to the comments.

Indentation is not perfect, but pretty good. Not sure how to perfect, given the difficulty of testing the last char written.

Added StyledStreamWriter, which has no reason to derive from Writer, since its write() method does cannot return a string and must take a stream.

Added prop svn:eol-style native. Stripped carriage-returns on unix. Hopefully, this will work for Windows too now.
