Close Gajim window on Escape

I've used gajim many years (in Linux) so I'm happy to see the new UI.
However, there are three small things that I really would like to see:

1. Popup the window on new messages.
   Yes, I know it can notify through D-bus, but they disappear after a while and the I usually miss the message. :-)

2. Popup the window when clicking on the status icon.
   Now I must first click on the icon to get the menu and then on Show/Hide window. If the window is already up but hidden under other windows I'll need to click on the status icon again.

3. Close the window when pressing the Escape button.
   That would be so much easier than clicking on the 'X'-button.

These are some small enhancements that would make Gajim even greater! :-)
