Re-implement focus follows mouse for outputs 

That is, moving your mouse pointer to a different workspace which does not have
any windows on it yet will correctly update the focus.

/* While usually this function is only called when the user switches

* 1) the user actives a new output (say VGA1).
* 2) the cursor is sent to the first pixel of the new VGA1, thus
* generating an enter_notify for the screen (the enter_notify
* is not yet received by i3).
* 3) i3 requeries screen configuration and maps a workspace onto the
* new output.
* 4) the enter_notify event arrives and c_ws is set to the new
* workspace but the existing windows on the new workspace are not
* focused.
