Webplayer can now handle a basic playlist, pushing multiple songs in the
playlist and passing from one song to another.
Some things that are not yet working:
* Using previous and next buttons and going outside of the playlist
breaks things.
* Random / repeat modes are not yet implemented.
* Playlist is not exposed in the UI at the moment.
* Seeking in a song is not exposed in the UI.
* When playing a song, webplayer does not automatically play the next
one when reaching the end of the song.
Major code review, cleaning the code and adding a lot of comments. Also
implements a separate store to keep entities with a reference count and
garbage collection. This closes#15.
Known issues at the moment are:
* Webplayer is no longer working, it has to be refactored.
* AlbumPage is to be implemented.
Now able to play a single file, in a format supported by your browser.
* Playlists not yet supported.
* Volume is a simple on/off switch.
* Repeat / Random not yet supported.
Also includes misc fixes
* Use CSS modules for all the CSS.
* Fix a bug in the filterbar which was not filtering anything.
* Fix a l10n issue in songs view.
* Update hook to clean build repo before running, preventing to push
dev built code.
* Update webpack build code.
