Decay of non-capturable structures.

[mimo]

Some structures (like walls or field) are not capturables. And thus, because all the decay logic is now done inside the Capturable component, their decay has no effect and they always keep their initial ownership.

One way to fix that behaviour would be to nonetheless give them a Capturable component with a NonCapturable attribute, but that would complicate the code and gui for a very small benefit. The other way would be to let the TerritoryDecay component manage the decay of non-capturable structures, either by duplicating the code of Capturable, or just having a simple immediate decay when not garrisoned.

At first, I was preferring 2 but finally 1 is perhaps better. It's good to have that option to capture by territory but not by attack. Can't we do that in the converse way, i mean adding a RestrictedClasses system (with the Wall classes) to the capture attack (so we have not to complexify gui and code) ?

[fatherbushido]

Well, adding Capturable component to walls and RestrictedClasses Wall to units capture attack works nice but: refs #4220

Not sure, but was it intended, that Athenian long walls (can be built in neutral territory) and roman siege walls (can be built everywhere) also decay? You need to garrison them all the time. And Gates will always decay, because you can't garrison them, so they will be useless for the siege walls and the athenian long walls.

Add uncapturable special filter and use it on Danubius to prevent the palisade walls from being captured right at the gamestart following r19694.
Arbitrary special filter AI compatibility was added by r20162.

I suppose it would be consequential that walls that can be built in enemy territory do not decay and walls that can be built in neutral territory only decay once the entity stands in enemy territory(?)

Yeah, that's how I think it should work.

Move tickets to Simulation as UI & Simulation got some sub components.
