Opportunity to back out when loading a save game with missing parts

[Dunbaratu]

When you load a saved game sometimes some of the vessels in the saved game contain parts that are not in the parts database (usually because they were from mods that were either deleted or failed to load because an upgrade of KSP rendered them incompatible). When this happens the game opens a popup message warning you that the vessel had to be deleted from the game because of the missing part. This could occur for several vessels. What I would like to see is an option in the UI at that point to say "NO! Please don't load this campaign - go back! Abort! Abort!". When this has happened in the past I've found that the only way I have to save the state of the saved game and not delete ships from it is to kill KSP externally. Once it gets to the point where it is showing you the Space Center screen it has already saved a checkpoint of the persistence file, with those vessels gone.

Oh totally. If the game sees that some craft will be deleted it should say "Craft will be deleted, continue with load?"

Then you could revert or load as is your wish. A list of parts causing the issue would be a big help too.
