Fixes a regression from 2c435c0506 - where the support actors must be able to path to the base actor in order to prevent them from spawning in isolated areas. If the base actor is immovable, they cannot path onto it because the base actor blocks them, so no support actors will spawn.
Fix this by allowing the support actors to path back to any cell adjacent to an immovable base actor, rather than requiring them to be able to path to its location directly.
When spawning starting units, or spawning units when collecting a crate, nearby locations will be used. If a nearby location cannot be reached, e.g. it is on top of a cliff or blocked in by trees, then any unit spawned there will be isolated which is not ideal.
Use the PathMightExistForLocomotorBlockedByImmovable method to filter nearby locations to those where the spawned unit can path back to the original location. This ensures the spawned unit is not isolated.
- Add prefixes to all message keys to provide context
- Use messages with attributes for some UI elements (dropdowns, dialogs, checkboxes, menus)
- Rename some class fields for consistency with translation keys
Prior to ef44c31a72eab61a597cf539ee4b138e94b254fe, Locomotor would be earlier in the trait initialization sequence than SpawnStartingUnits. After this commit, the initialization sequence was perturbed and SpawnStartingUnits would initialize first. When SpawnStartingUnits would query CanEnterCell this would generate a null reference as Locomotor had not yet initialized.
SpawnStartingUnitsInfo is made to initialize NotBefore LocomotorInfo to enforce the required trait ordering.
