Improve downloader

[0scvr]

The url of the opened page is what's used to download songs with the downloader plugin. This is a problem because it means that the song needs to be "opened" to be able to download it.
I often find my self trying to download a song from search results by clicking on the 3 dots menu on the side, only to find that the plugin is using the url of the search results and not the url of the song and therefore doesn't work.

Hey @devstra, thanks for the feedback! This is a known issue that should be fixed by #213 (merged, it will land in the next version), downloader will now use the current song being played instead of the current URL!
