Hook up some buttons for navigating history (undo / redo). Some refactoring to allow for the audio player to get updated as a consequence of a state change (the audio related to the current top of the stack is used).

<button md-icon-button (click)="emitToggleRecording()">
  <md-icon>
    <ng-template [ngIf]="recordingStatus == 'enabled'">mic_none</ng-template>
    <ng-template [ngIf]="recordingStatus == 'disabled'">mic_off</ng-template>
    <ng-template [ngIf]="recordingStatus == 'recording'">mic_on</ng-template>
  </md-icon>
</button>
