Frontend-GNOME: hide expanders of chat tree (closes: GH-146)

The expanders of the chat tree were never part of the design spec and introduced
new issues I don't want to deal with for now.

Known issues:
 * wastes some vertical space because of the expander icon
 * collapsing hides highlights
 * collapsing deselects the active chat and breaks executing any command

Engine-Twitter: Delay the UI usage in the timeline command

The timeland command should launch the new chat only when it has
retrieved all data needed for the chat.
Engine: Execute the OnConnect Commands in a thread

They could take some time so it is better to launch them with the
threadpool, in case the Connect() method is synchronous.

Frontend-GNOME: fall back to Smuxi / session chat if no chat is selected

Falling back to the Smuxi chat is important when you close a chat as it loses
the current selection and then you can no longer issue commands, see GH-146.
