Hiding results list when you click outside the search bar

[bencodrington]

When you have text in the search bar, you should be able to hide them by clicking anywhere outside of the search bar, allowing users to maintain text in the search bar without having the whole page blocked by results.
This would be especially useful when trying to click multiple tags on existing tracks to create the search text from that.

Note that clicking in the search bar again or clicking an existing tag to add it to the search bar should re-show the results, and update them if necessary.
Second note that maybe the maximum height of the search result list should be 1/2 the total screen height on mobile & small resolutions to ensure that there is always free space to click to activate this feature.
