Fixes localization reload mechanism for .string files at root (only 1 language)
CascadingTree : Manage inheritance priority for complex inheritance chains.
Removes ColorPalette.
Implements Value injection in CascadingTree.

CascadingTree now provides two ways to organize the data : Inheritance and Injection

Inheritance allow multiple inheritance and overriding of key value sets and hierarchy.
Injection allow to replace a value for a specific key by referencing true value defined elsewhere in the cascading tree.

Here is an example of data injection :

{
     "ColorPalette" : {
         "MyBackgroundColor" : "redColor"
     },

     "UIViewController" : {
         "view" : {
                "backgroundColor" : "ColorPalette. MyBackgroundColor"
          }
     }
}

In this example, the background colour of the view in UIView controller will get the value of ColorPalette.MyBackgroundColor injected and will be red as a result.

Injection could be very useful to group colours or metrics for the UI. By grouping this values in dictionaries we can externalize a whole set of attributes for the UI in specific files that we'll import where needed.
Another advantage is that we can wrap it in @ipad or @iphone and by this way defines metrics or colours that are specific for a device and use the same key path to inject the values in your layouts and stylesheets.
CascadingTree : Bypass data injection for reserved keywords.
Cascading tree : bypass injection for all keys beginning by "@" which are considered as reserved keywords.
Fixes Container and split view controller multiple calls to viewwillappear on iOS >= 5.
Fixes SplitViewController setViewControllers with animations.
Removes nslog
CKCollectionTableViewController : Fixes layout of tableViewContainer when the searchBar is displayed when the keyboard gets dismissed or sizeToFit gets called
CKContainerViewController : Fixes sub view controller navigation item presentation on ios6 & ios7.
CKContainerViewController : Fixes non KVO complient key toolbarItems. Cannot bind on it for an unknown reason (ASK APPLE)
Fixes CRAH when reloading a stylesheet from the resource manager and having layouts in navigation item title view.
Layout : Fixes prefered size when sub layout box could have an infinte width or height.
CKViewController : Fixes styleview artificial grow for toolbar animations.

The styleview in some cases could have 44 pixel height more than wanted.
UIImageView + Layout : preferedSize is computed using the image's size + padding. an optional flexibleSize attribute can be set or we still can specify fixedSize or maximum/minimumSize
Merge branch 'master' of github.com:wherecloud/AppCoreKit
UIImageView + Layout : If constraints when computing preferred size is smaller than the image, computes a size that fits in the constraints and that respects the image's aspect ratio.
