Add auto-download functionality

New function added to the settings screen allowing you to turn on auto-downloading (for offline) of tracks when you play them.

Improved player screen, add to library from search results, search from player screen

New features and improved UI of player screen.

Now you can:

• click on the artist or album on the player screen to search that text
• add a search result song to your library
• offline downloading is improved to not accidentally cache an empty track

Brought ytdl functionality down to app

To improve streaming capabilities, reduce risk of being blocked by youtube, etc, I've moved the code that works out the target youtube stream url down to the app.

The benefits here are that you can seek through a stream now, and hopefully downloading songs offline will be more reliable.

0.2.2 Removed search dependency on server

Due to issues trying to get working api keys, this release uses the local device itself to fetch the itunes search results and then queries youtube itself to get the matching videos (lazily to avoid throttling).

0.2.0 Offline songs

v0.2.0

Update to 2.0

0.1.0 Initial Relase

This initial version allows for displaying your synced playlists, caching them for the next app open.

Be aware it does not include song caching so expect every single play to be loaded over network. This is a high priority to be fixed in a later version.
