Let's fix damn resistance to foreign occupation

[taw]

I'll start. Here's result of exporting .empire_save, one turn after taking Venice (which shockingly turned out to have resistance 13 to Austrians, not 30 ...):

All these -12 can mean only one thing - resistance to foreign occupation.

Here's Bosnia, taken one turn before:

-11 just as expected. It's interesting how for Bosnia (taken from one absolute monarchy
by another absolute monarchy) - middle class has zeroes (except for that last -11),
while for Venice, there's a lot of leftovers in middle class section.

What do we do next?

Annotation time. Am I on the right track here?
It all comes from .empire_save after a few turns as austria.
