adding a package.json file
Merge pull request #11 from stephenmathieson/add/package.json

Adds a package.json file.
Added functions to parse file with comments and new tests.

json_parse_value_with_comments and json_parse_string_with_comments replace comments with whitespaces before parsing. Supported comments are: /* */ and //
New lines after flow control statements are now consistent.
Fixed warnings and error resulting in printing string without comments (old debug statement).
Fix memory leak

If `fread` fails, `file_contents` is leaked.  I’m just freeing the memory allocated :)
