Include sounds in the extras task.

Copy the sounds to dist/ as part of the extras task instead of creating a
separate task.
Remove ionsound as a dependency.

Use HTML Audio objects directly to handle sound playback so that we can
observe events and update the UI accordingly. Add Vue as a dependency and
create a SoundEffect Vue component that handles playback of sounds and
displays feedback in the UI including icons for when the audio is playing
(using font-awesome) and keeping track of the play count.
Implement a progress bar.

Dispatch a 'playbackProgress' event from the sound effect component. Listen on
the root view model for that event and update a progress bar to indicate how
much playback is left.
Remove the Dinglake tests.

Remove the Dinglake test spec because the Dinglake object is no more.
Bump to 0.2.0.
