Added additional message; added sample timestamp (unix epoch)
Added datetime header to threadlist. If timestamp of current message is different than previous message, datetime header is shown (i.e., group messages by datetime). TODO: consider using some library like momentjs to prettify the datetime header as well as compare by day (rather than current version that compares by epoch second).
Added style for datetime group header (.thread-list .thread-item-groupheader). Also, added .threads-list .selected>.thread-item to correctly show selected item since ThreadItem is now moved down one level in components for DataList
Changed mock data - changed folder from inbox to sent
Styling changes so sent messages appear different from received messages
Placeholders for avatar icons in message thread
Styling change to inputbox for typing in a new message + placeholder for send icon
Added header toolbar for the messages panel; shows displayName of selected thread
Copied assets to app folder; more styling changes; fixed avatar mask/icon

Added IM status icon; styling changes to im-status
