Applied Xavier's comments

Added "show-contacts" property in empathy-chat with default value to preference.
Setter function show/hide contact list.
When Conv menu is opened in empathy-chat-window, update it with "show-contacts" value.
Uses "remote-contact" instead of "empathy_chat_is_room" for that.
Call setter function when Show Contacts menu is activated.
