shutdown app read EIO error

[cyphunk]

When closing electron application there are some times errors such as the one below. Also the Aprspoof process will some times not give up its port.

Error: read EIO

syscall: 'read'
}

This also shows up on OSX. Do not have time now but later test:

• remove tty code from packets.js and see if this issue persists when closing electron app. if it is a tty hold issue consider adding flag for not grabbing tty and use the flag when forking the process from electron.js
