json-cpp Code

fix stdexcept

https://sourceforge.net/p/jsoncpp/bugs/68/

Fixed a test that causes a crash when exceptions are disabled.

While I was at it, corrected whitespace too.

Added structured error reporting to Reader.

This allows applications for interactively viewing or editing JSON to do
a better job of highlighting errors. Also added offset accessors to
Value, offering the same sort of functionality even for non-errors.

Thanks to Zach Clifford (zacharyc@...) for the patch.

Added features that allow the reader to accept common non-standard JSON.

This is a version of patch #17, from Clay Wood:

Comment reading/write improvements

This patch fixes some aspects of reading and writing comments:
- Multiple C++-style comments before a Json value had extra newlines appended to them. This patch removes the addition of those newlines.
- Comments written before Json values in the StyledWriter were not indented to match the indentation level of the value. This patch adds indentation to comments.
- Fixed inconsistency in newlines following C- and C++-style comments being saved as part of the comment. All newlines at the end of a comment are now removed.
- Added an additional test of comments.
