Turned the non-functional Engineering Engine Monitor PDA app into a remote power monitor. Requires a functioning power monitor computer, if it's broken another should take over automatically if it exists or when you build one. First one to start up is the one that sends data to PDAs for now. Tested multiple power monitors at once, bombing and replacing computer. Didn't test dismantling the computer to see if that triggers the breaking code because it doesn't seem to be possible with this version of the power monitor.
