Revert "Use std namespace for snprintf."

[baruchsiach]

This reverts commit 1c58876.

std::snprintf() is only available in C++11, which is not provided by
all compilers. Since the C library snprintf() can easily be used as a
replacement on Linux systems, this patch changes jsoncpp to use the C
library snprintf() instead of C++11 std::snprintf(), fixing the build error
below:

src/lib_json/json_writer.cpp:33:18: error: 'snprintf' is not a member of 'std'

Careful! The C function in the global namespace is not guaranteed to
be provided by . If you want the C function you must include
<stdio.h>, and if you use you are only guaranteed to get
std::snprintf.

I included your commit in #232, plus something to address Billy's caveat. See #224 for more discussion.
