Compatible with iOS 11.
1. A Control Center toggle for turning SSH on/off.
2. A Settings menu for changing the port that OpenSSH listens on.
Add the toggle to ControlCenter from Settings>Control Center>Customize Controls.
If OpenSSH is turned off with this, either the toggle or from the Settings menu, then it stays off even after rebooting/re-jailbreaking (Electra).
For the ones loving the shell, it also includes the command SSHswitch which has the same functionalities, `SSHswitch -h` describes its options. No need to log in as root for it to work.
