Updated to Swift 2.2.

Fixes for Carthage 0.12. Added default Ind.ie ./dev and ./install scripts.

Added new designated initialiser where you can specify a link handler to handle links that are tapped in the status message.

Cleaned up the code a bit. Removed outdated print statements.

Worked around a bug where Application Did Become Active was sometimes being called later than usual, resulting in a clash with a state animation.

Added CCHLinkTextView as a Carthage framework.

Updated the readme with installation instructions for sub-frameworks.

No longer embedding the Handle framework within the StatusMessageWindow framework.

Now using Handle as a Carthage dependency.

Demo project will now compile when cloned by others.
