Focus existing window instead of launching another

[Cody Garver]

Slingshot should treat existing windows the same as the dock. Don't launch a new window from the .desktop if it already has a window open.

This depends on the application and is also affected by other ways of launching apps (i.e. command line or keyboard shortcuts), so I'm not 100% convinced it's only a Slingshot issue.

For example, apps like Music, Videos, and Photos don't spawn new windows but focus the existing instances. Midori and Terminal open new windows, while Files opens a new tab in the existing window.

But also make sure the user will actually be able to launch additional windows if wanted (right-click -> open new window).

There are always vailid use-cases for this, like multi-screen, comparing, mixing, ...

You're always able to drag a tab outside the window which opens it in a new window, so I don't see that as an issue. Pantheon-files behaviour seems correct, Terminal and Ephiphany still opens a new window using either slingshot or super+t.

I have a special key which opens a new "Files" window (not sure what the keybinding is), but this always opens a new window, although one may be already open and even focused.

Also, I can confirm that cmd+t always opens a new terminal.
