Add SDCAlertViewTransitioning protocol

This protocol is created to make give other developers the freedom to decide how to show and dismiss alerts.
Fix build errors and warning in SDCAlertViewTransitioning.h
Make SDCAlertViewCoordinator default coordinator

Most developers will want to use the default SDCAlertView transitions, so use SDCAlertViewCoordinator as the transitionCoordinator if no custom coordinator was provided.
Get rid of SDCAlertView_Private.h
Revert "Update to version 1.2.2"

This reverts commit 264ad0c29d56bfda081aad27c8f711ec58bb5b06.
Use self.transitionCoordinator for transitions

This uses the protocol methods from SDCAlertViewTransitioning on self.transitionCoordinator instead of SDCAlertViewCoordinator directly.
Automatically update constraints when showing alert

An explicit call to setNeedsUpdateConstraints was required after an alert was added to the view hierarchy, so that the alert knew what size it could take (should it need to expand due to large content). That call is now made automatically when the view is added to the view hierarchy, which makes it easier for custom SDCAlertViewTransitioning objects to be implemented.
Improve documentation
Enable iPad target in sample project
Set deployment target for sample project to 7.0
Remove potential animation side effects

As discussed in #25, some views created by Apple animate when added to a subview, which could potentially interfere with the alert animations. By removing the addSubview: call from the CATransaction, the completion block for that transaction will always only be called after the animations relating to alerts have finished.
Use tintColor for button titles

Instead of hard-coding the system’s default tint color, SDCAlertViewContentView now uses self.tintColor for the button titles. That means that setting tintColor on an alert will affect the alert’s buttons as well as any alert subviews that use the tintColor.
