Y.mix() will no longer shadow prototype properties on the receiver by default. [Fixes #2530501] In 3.3.0 and earlier, when doing an object to object mix, a property "foo" on the receiver's prototype would block a property "foo" from being mixed into the receiver itself if overwrite == false. In 3.4.0, prototype properties are ignored during an object to object mix, since that's essentially the definition of what an object to object mix is (i.e., "mix things from this object [not its prototype] into that object [not its prototype]"). After much discussion and consideration, we've decided to bring back the old behavior to preserve backwards compatibility. While the old behavior violates the strict definition of an object to object mix, the new behavior violates the principle of least surprise, so the old behavior is the lesser of the two evils. One side effect of the old (and now new again) behavior that should be noted is that since shadowing of prototype properties is never allowed when overwrite is false, using Y.mix() or Y.augment() with an object or class that contains a toString() property (or any other property that exists on Object.prototype) will result in that property not being augmented. The only way to augment an object with properties that would shadow those on Object.prototype is to set the overwrite parameter to true. This caveat would also apply to properties added to Object.prototype by other JS on the page (Object.prototype.toJSON comes to mind).

Refactor oop tests.

Fixed IE error when the delete operator was throwing for certain objects.

test update

Classes that implement an 'each' iterator like NodeList and ArrayList will have that each function executed if an instance is passed to Y.each -- this isn't new, but it was preventing these classes from using some of the inheritance functions. The inheritance functions have been fixed so that this now works. [fixes #2528555].

DOMReady tweaks [fixes #2528304]. Removed redundant init code.

Added Y.Array.forEach as an alias to Y.array.each in the collection package.

Fixed recursion problem when an object passed to Y.clone has a property that is a reference to itself.

restored hasOwnProperty check in merge/mix

each/some do not throw when passed non-objects [fixes #2528342].

Any given object is only cloned once. DOM element attributes are not cloned. [bug #2528250].

Added special handling for Nodes to clone [fixes #2528250].

Initial custom event split

API revamp. Corrected Event.Target and Event.Custom refs (now EventTarget and CustomEvent).

removed context arg from Y.cached

test update

queue metadata update

bind() supports a string representing a function to execute on the context object in order to allow subclassing of bound methods.
