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).

<input #open type="file" accept="audio/*" (change)="decodeAudio($event.target.files)"/>
<button md-icon-button (click)="openAudioDialog()">
    <md-icon>folder_open</md-icon>
</button>
