Make reconnections actually work

Browse Source 
At the moment, the reconnect feature is somewhat glitchy, popping up
multiple reconnect prompts even if a reconnection succeeds, and
occasionally causing crashes.  A successful reconnection results in the
conversation history being cleared, which is an annoying outcome when
connected over an unreliable network.

This patch does the following:

* Keep track of whether a reconnect dialog is active, to prevent
  multiple dialogs from opening.
* Introduce a new field to the Server object, mayReconnect, which is
  used to keep track of whether a reconnection should be attempted in
  the event of a disconnection.  It's set to "true" when we connect to a
  server, and "false" if the user asks for a disconnection.
* Prevent the clearing of active conversations and conversation history
  on disconnect, unless the user specifically asked for the disconnect.
* Keep the IRCService running even when no servers are connected, unless
  the user has disconnected from all servers herself.  This is needed
  for reliable auto-reconnects (see next patch), but has the side effect
  of keeping conversation history around even if the activity isn't open
  when a disconnect happens.
