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.
Features:
* Now displays the number of mentions that the user has not seen in the
notification.
* When no mentions are outstanding, display which servers the user is
connected to, not the last message.
* When more than one mention is outstanding, display the names of the
conversations with new mentions, not just the last message received.
* Notifications of mentions are suppressed if you're in the conversation
at the time of the mention.
* Notifications of mentions automatically clear when you bring up the
conversation.
* Vibrate notifications now generate the user's chosen default vibrate
pattern, not a hard-coded one.
* Add ticker text to the notification that's displayed when the IRCService
goes into the foreground, instead of displaying a blank ticker.
To allow for all of this, the implementation moves most of the details
of generating the notification text into the IRCService, which now
exposes addNewMention() and notifyConnected()/notifyDisconnected()
methods instead of the lower-level updateNotification().
