Merge pull request #5 from icedream/migration

Migration to newer "node" base image. Closes #4 and #6.

This will provide a newer version of node along with a newer base OS that allows us to make use of new libvlc binaries as well that have OPUS support. This is important to get YouTube support back working as youtube-dl -f bestaudio tends to select OPUS streams for newer videos.
