While investigating some memory leaks it was unclear whether the JSON code correctly free'd all memory during parsing. Add a test case which can be run under valgrind to clearly demonstrate that the parser is leak free. * tests/Makefile.am: Add 'jsontest' * tests/jsontest.c: A few simple JSON parsing tests
