Hide MainWindow on Esc key pressed

[dlopezleon]

I'm pretty much a freak of keeping my traybar clean of unimportant windows. Because of that I close everything and put the important ones in the traybar. That's why I want that this action made done as easy as it gets, i.e., pressing repetedly the 'esc' key. So if I'm talking to somebody, I say my last sentence, press enter to send, and I want to press esc until every emesene window is hidden. I attach a patch for doing this.

chinese need a clean esc button, so you must make an option if you want to have it applied
