remove sigchld function

Explicitly setting the handler for SIGCHLD to SIG_IGN tells the OS to
reap zombie processes automatically, which is what we wanted anyway.

added redirect from stdout to stderr for spawned processes to prevent conflicts with the statusbar outputs

Fixed tab formatting in 6 locations where statusbar() is called

Changed output to stdout instead of a file

updated output format for better expansibility and easier parsing
