Thanks for Mateusz Loskot for the fix.

Extend the run_output_test() function so we actually can pass command line
 parameters and so we can support different output files for the same test
 executable.
Also provide some hints about what to do if a test fails (i.e. set VERBOSE=1).

There are now three options: JSON_C_TO_STRING_SPACED, JSON_C_TO_STRING_PLAIN and JSON_C_TO_STRING_PRETTY.
This also add a json_object_to_file_ext() that takes the same flags.
Existing output of json_object_to_json_string() is unchanged, and uses JSON_C_TO_STRING_SPACED.
Thanks fo Grant Edwards for the initial patches.

that, since not all environments actually have a stdbool.h to use.

Clean up documentation and correct sample code

Fix missing inttypes.h definitions for Visual Studio 2010 and earliers. ...

Add new iterator implementation and some NULL-pointer safety

Additional explanatory comments

New json_object_object_get_ex() method protects itself against null pointers
and invalid objects being passed in.

New lh_table_lookup_ex() method protects itself against null pointers
and invalid objects being passed in.

Change the resize check from "count > size" to "count >= size" to avoid a
potential infinite loop with high load factors and a full hash table.

Renaming the boolean type to json_bool in json_object.h

Fix a typo in the string represenations of the json_tokener_error_depth error (s/to deep/too deep/)

In building large systems, there are often clashes over the
preferred base type to use for bool/boolean. At least one
experience has been with a 3rd party proprietary library which
can not be changed. In that case, boolean was a synonym for
unsigned char and used widely in packed structures.

Add documentation for the json_tokener_parse_ex() function.

As part of this create a public json_config.h with a custom define to
decide whether to include inttypes.h to avoid conflicting with other
projects config.h header.
