More clear output for process name
Currently it uses /proc/{PID}/cmdline
as the process name, in order to avoid the issues in comm
or status
(e.g. truncated name; the name of interpretor rather than the real program).
However, some programs don't use cmdline correctly (e.g. do not seperate args "correctly" using '\0') and some are displayed with the full filename (including path).
This should be resolved.
