SSH in, suspend attack, do stuff, resume attack

[Struthian]

I would like to SSH in, suspend an attack underway (keyboard would still work for the person using it).   I could then mount udisk, grab the loot, make changes.  Another command would resume the attack. That command should  have the option to resume the suspended attack or load a new  payload.txt and start with that.

A command to return to attack mode would be useful when connecting by serial port.
