Added coveralls support for json_module.f90

 - Fixes #63 : coverage info
 - skips coverage info about the tests, since the tests exist only to test json_module
 - currently only one build, the build.sh script will produce the coverage info and
   will update coveralls since doing it from multiple builds is redundant.
