feat(overlays): refactor logic for selecting current overlay
Do the selection in mapStateToProps so the container itself doesn't need to
receive all the props that each overlay needs.
Each overlay is responsible for fetching their own props and for providing a
"needsDisplay" static method wich will be called with the full redux state and
should return true if the overlay needs displaying.
Also eliminate duplicated state keeping: the connection and conference error
states can be fetched from their respective base features.
ref(overlays): Replace the abstract class for overlays with overlay frame component
In this case makes more sense to have overlay frame included in every overlay instead
of abstract class that implements the overlay frame and have to be extended by every
overlay. In addition, mapStateToProps isn't working well with inheritance.
