Component/Container: overriding static init
Component/Form: validators call with form context
Component/InfiniteContainer: allowing .bind() for firstLoad

firstLoad as a flag couldn't be used without model before. This change
fixes that.
Controller: contained entities in .nests

.nests should be an object of other entities. The keys of that object
should match the keys of the view's .nests. The view's .nests is an
object of selectors, such that matching .nests keys will have the entity
rendered into the selector.
