add RecursiveGetAllEntitiesWithComp

[SolStar2]

added functionality in container system to get all entities with a component recursively. This will help in situations in which all entities with a certain component needs to be processed before a parent container does something. Such example as a polymorph dropping all MindContainerComponet entities before polymorphing so they are not sent to null-space.
