Moves isVisible & isFirstResponder observers into rendered state rather than attached state so that we can queue visibility changes when rendered but unattached.  Includes passing unit test.
Fixes the _doRender method of the view to not attempt to attach to a parent if the parent isn't rendered.  Solves the case of rendering a child view before the parent itself is rendered.  Fixes failing unit tests.
Removes the long deprecated SC.Border mixin.  This capability was brought into SC.View several versions ago.
Adds cleanup to several unit tests in order to avoid leftover views from corrupting later tests.
Updates the collection fast path unit test to be more accurate and work properly.
Removes additional redundant observer on SC.ListView.
Updates a unit test to remove references to code that no longer exists.

Removes improper delay on updating view content.  Otherwise it would be possible to change the view state before attempting to update the content.
Refactors the SC.View and SC.ContainerView transition plugins and protocols to be more accurately named.  Adds bounce and spring adjust transitions.  Turns on container view's swap transitions.
Removes attempt to animate centerX & centerY along with width and height respectively, when the change in width or height is less than 2 px and wouldn't cause the margin-left & margin-top layout styles to actually change.
Fixes up the BOUNCE_ADJUST and SPRING_ADJUST transitions to work properly.  Adds extra options: `bounces` & `springs` to set the number of each.
Updates the documentation for all of the adjust transitions to indicate the available options.
