Oil processes

Oil has an alternative way for managing processes.

The biggest difference is the fork and forkwait keyword which are blocks.

fork {
  sleep 4
  write -- "Hello world"
}

forkwait {
  sleep 4
  write -- "Hello world 2"
}

fork is the alternative to the & operator (e.g., sleep 6 &) which can be blocked with the wait keyword.
forkwait is the proposed alternative for subshells.
jobs views the jobs and processes of the shell.
fg brings a job into the foreground.
