The Failsafe can now recover from an deleted MC (#60846)

* The Failsafe can now recover from an deleted MC
Its also more reliable and can handle a situation where its main Loop runtimes and the MC is stuck

* Reset defcon level correctly
Oops left that in from debugging the levels

* Correctly recover SSasset

* Only decrease defcon if MC creation failed
Also add some sort sleep between emergency loops

* Makes the last two emergency actions manual procs
Since they are kinda unstantable its probalby best
if only admins call these manually

Its also more reliable and can handle a situation where its main Loop runtimes and the MC is stuck
You can also now debug Master/New()

While there will most likely never be any situation where the MC is just gone its still good to know that the game can recover from such a situation
For example maybe someone messed up a SDQL query or maybe someone wanted to delete the MC to create a new one hoping the Failsafe would do so for him
