Refactored the timeline notifications so that actual timeline objects are being passed. Conversations, when selected, now appear as a timeline (with dummy path, etc.)

Created the Delay library based on the earlier functional version. Renamed handle.swift to Handle.swift.

Added a dampner (and implemented cancellable delayed block execution) to the profile image component so that it doesn’t flood the image snapshot routine when the user is actively manipulating the image editor component.

Updated the delay function to add option to return on same stack frame. Setup process now intelligently decides whether to give VoiceOver time to read state transition messages by delaying the visual state transition.

Added some string extensions for easy string replacement. Updated my NSNotificationCenter extension with methods to remove observers. The setup steps now pass data between each other. The second step of setup now tries to present user’s handle in a more human fashion, pre-populated in the name field (progress towards #25).

Started implementing a notifications-based interface for remote procedure calls. Trailing and leading hyphens are now trimmed before the call to check if handle exists is fired (closes #20).
