Implement IPC binding event (keyboard)

This implements the IPC binding event for keyboard bindings.  It is
slightly different from the i3 implementation [1] since sway supports
more than one non-modifier key in a binding. Thus the json interface has
been changed from:

    {
      ...
      "symbol": "t",
      ...
    }

to:

    {
      ...
      "symbols": [ "t" ],
      ...
    }
