Download manager.

[jarro]

Just some minor things from listener emails.

• Download manager doesn't retain your bitrate setting.
• The download length slider is too short. Should be 10 hours. Especially since the download manager is single threaded. Downloading a few days of music is very tedious.

@donshefer in the next big revision let's extend the slider to the 10 hours. We should probably have a warning pop-up to keep the app open for anything over the 2 hour mark as backgrounding the app seems to bork some downloads.
