Re-enable logging, make appending messages to ConversationView safer

Now all instances of sending messages (bar status changes) to a
conversation's CayaRenderView only happen when attached to the window.

Messages sent by user appear after the protocol confirms it's been sent
(IM_MESSAGE_SENT), rather than appearing right after the user sends it
to the protocol (IM_SEND_MESSAGE).

Logs are now re-enabled (since they can safely be appended under any
circumstance).
