[MalKeshar]

Tested with 2.9, 2.10 atop versions.
Usual output has this field, but json output has not.

Indeed, "parsable output" (-P flag) prints "process name" fields (ps->gen.name) after PIDs, but json.c output misses those.
Was easy to fix. Submitted PR #299, which fixes the issue.

Process name added to JSON output via PR #299 (renamed 'name' to 'cmd' and removed parenthesis).
