Update generic process field display

- sort cases by identifier
- use check snprintf
- color nice value of 0 as gray
- color cpu and memory percentages of 0.0 as gray
- color number of threads of 1 as gray
- color idle and sleeping state as gray
- color tgid matching pid (indicating main thread) as gray
