Import PSDs from old branch, change default avatar
Forgot the rule about small commits; expand me...

- Attempt to fix "CATransaction deleted..." errors I was getting.
- When DESFriend->lastSeen is 0, display a different, less confusing, message
- SCUnifiedWindowController displays status and name of selected friend in title
  bar.
- SCUnifiedWindowController and SCBuddyListController display number of DHT
  nodes in title bar.
- Fixed wrong selector being checked for by callback
  _DESCallbackFriendStatusMessageDidChange.
- Fixed SCAddFriendSheetController checking for PIN that was not required
  (and thus crashing)
- Fixed validation of plain IDs.
- Import the styled text field from Poison 1.x - rewrote drawing code to use
  only Quartz methods
- More intelligent date formatting for friend list cells. The date is now
  omitted only when the date being formatted is the same as the current date.
- Clicking on the avatar now pops up the selfMenu.
- The name/status editing sheet no longer pops up when you finished dragging
  the window with the cursor over them.
- Dump Tox state more often.
Update TLs.
