net::ERR_FILE_NOT_FOUND for sound files

[dschuessler]

I wanted to set up a development environment for fixing issue #16, but development builds don't have audio. It turns out Kakapo can't find the audio files. Here is the log of the desktop app:

The mentioned sounds directory does not exist. The sounds are in node_modules/kakapo_assets/sounds/ and are properly converted to OGG. No difference between the develop and the master branch. I'm at a loss at why this happens and would appreciate any help.
