Feature login command
Added a trigger for a SignInCommand script when Sign In is done.
if defaults.string(forKey: "SignInCommand") != nil {
let myResult = cliTask(defaults.string(forKey: "SignInCommand")!)
myLogger.logit(LogLevel.base, message: myResult)
}```
This will trigger at:
1. autologin on launch
2. autologin on using menu item if everything is set
3. at end of login in LoginwWindow.swift
4. at end of password change at LoginWindow.swift
