combine all of the reducers into one meta-reducer

combine_reducers.ts

const developmentReducer: ActionReducer<IAppState> = compose(storeFreeze, combineReducers)(reducers);
const productionReducer: ActionReducer<IAppState> = combineReducers(reducers);

// our meta-reducer will take care of forwarding all actions
export function AppReducer(state: any, action: any) {
  if (String('<%= BUILD_TYPE %>') === 'dev') {
    return developmentReducer(state, action);
  } else {
    return productionReducer(state, action);
  }
