`Animated` property in background plane not reflecting texture type

[Krzyhau]

I assume that Animated property for background planes is disabled to prevent people from putting it in invalid state (as in, having Animated flag set for regular textures and vice-versa). However, right now, this property is not actually synced with the type of the texture - newly created Background Planes will have this flag disabled, causing maps created with them to crash, as the game is expecting specific texture type according to this flag.

It makes sense to make it read-only, since it depends not on the properties of a particular instance, but on the background plane asset itself. Unless, of course, there are levels that a static instance with animation has or vice versa.

I understand, and that's not my concern. My concern is that the flag remains unchecked for animated textures.
