Singular Instance Failsafe Terminator

[NathanCheshire]

On startup, if a singular instance is detected, give the user the option to attempt to terminate the other session if they enter a valid username and password combo for that instance of Cyder. If right credentials, try for that other Cyder to unbind, exit, and return exited to the foreign instance so that it can proceed. The other instance should be well within its right to refuse termination so that the other user cannot start a new instance.

Should be an ini prop to accept remote close requests as well as an optional password.

Testing might be hard for this but theoretically if you can close yourself using this temporarily with some commented out code for debugging purpose, it should work for different users. My only concern is the process sleeping.
