Added ability to quickly display partial results on Song Info and Artist Info Panes.
Increase default timeout for loading song/artist info.
Now we don't wait for everything to be loaded before displaying the results, it seems fine to wait longer to get all the replies.
Also, it doesn't seem necessary anymore to allow users to change the timeout setting.
Add possibility to download album covers automatically when playing a track without one. To activate: right click on now playing widget and select "Search automatically".
Minor codestyle fix
- Move sha1 cover hash to utilities
- When initializing song check if we have a cover art. If not, check if there is one in the cache and use this.
Network remote: send md5 hash along with library and files.
