Track instability values in mock age director
Eforen on the Mystcraft discord wants to know how to track the instability of the symbols added in a book.
We can't track instability from runtime resource values, but we should be able to track the static instability that some symbols add.
This should be a simple enough task, just need to modify the two methods below to track accumulated instability.
