console shortcut issue: change global shortcuts to in focus only

[pietrop]

This would be a way a round to make sure that console shortcut cmd + alt +j
does not ovveride other app such as chrome shortucts.
Could use focus and event lister to add and remove global shortcut from app when is not in focus

http://docs.nwjs.io/en/latest/References/Window/#synopsis

//get the window 
var gui = require('nw.gui');
var win = gui.Window.get();
//listner
win.on('focus', function() {
    console.log('New window is focused');
  });

in lib/app/app.js line 60.

Another option is to use mouse trap js. Which is what is used for the keyboard shortcuts in transcription show page. Would need to figure out a way to set this so that it works on every window.
