Closing Empathy chat by 'escape;

Standard shortcut for closing empathy chat tab is 'Ctrl+W'. Thanks God, it's possible to reassign it to 'escape':

1. Open /usr/share/empathy/empathy-chat-window.ui;


2. Change '<accelerator key="W" modifiers="GDK_CONTROL_MASK"/>' to '<accelerator key="Escape" />';
