treat multiple lines in text as separate searches

As described/requested in quicksilver/Quicksilver#1879

This would allow you to select lines from a file, like

    Opeth
    Mastodon
    The Sword

and search for them all individually in one shot.

One thing it will break, however: If you have a search URL for Google Maps, you will no longer be able to select a multi-line address and search for it as-is.

So decide which use case you think is more important and either close or merge this. I have no strong feelings either way.
