Re-sequentialize locals-sequential test.
Add a failing test for locals recomputation.
Compute locals via a static method.
Unbreak local-app-state-change test.

Do a setProps on the args if the app state changes on a toplevel
component.
Allow a :literally clause in letdom, for testing.
Add reacl.core.react-class.
Keep locals up-to-date on embedded components, too.

Unfortunately, that means stashing a copy of the locals in the state.
