Added favicons and title to dashboard and intro page. Issue #40.
Added an indication that a conversation is private (if the first message in a conversation has privateMessage set, mark the convo next to the service icon). Issue #18.
Change to Twilio message receiving to use Identity (Issue #48) and to use a consistent creation time (since the Twilio service does not provide one, just use the receive time but use one LocalDateTime to be sure they're all identical) (Issue #61.)
Added Subject field to Conversation. Facebook uses 40 characters of first message. Twitter uses provided snippet. Email uses the MIME Message Subject (or (no subject) if none was present). Twilio uses the first text message. Reddit uses the post title (removed the title from the Message body). Changed UI to use convo.subject. Issue #62.
Resized Email service icon. Issue #31.
Removed privateMessage from Message.java and moved the field into Conversation.java as privateConversation, and made the corresponding changes on the UI side. Also changed the Twitter code that sets/gets the field (for DM handling). Issue #18.
