Add search function

[Milinator]

Hey there,

First of all, I would like to express my praise to everyone involved in creating this, really nice!

In another thread I read that the songs are searched by fetching the meta data and then downloaded through one of the existing sources.

That's when I came up with the idea that a search function within the app would probably not be too complicated to implement. So instead of the link, you can simply enter a search term (song name) and then suggestions for downloads (sources + name of the song) will be displayed.

Best regards
Milan
