#63 ESC for Center Settings Window does not work

[Evgeny Bogdanov]

When we use "set_close_listener" to be able to close window on escape it does not work
for Center Settings Window or other window that has input text fields.
If there are no text fields it seems to be ok.

center_settings_window.js
// TODO: find out why bug appears, input field can't be edit when set_close_listener is used
// should be the same with all windows
// this.set_close_listener();
