Restore the terminal if a goroutine panics

Most goroutines run their function through utils.Safe, which closes
the screen if the function panics. Without it, the panic is printed to
a terminal that is still in raw mode and on the alternate screen, and
the terminal needs a reset afterwards. Go has no process-wide hook for
panics, so every goroutine has to do this itself.

Use utils.Safe for the goroutines that don't use it yet.
