Use ASDisplayNodeScreenScale().

ASImageNode and ASHighlightOverlayLayer were both using
[[UIScreen mainScreen] scale] directly.  Bad.  No cookie.  Use
ASDisplayNodeScreenScale() instead.

(Also, regenerate Xcode project with Xcode 6 and current CocoaPods.)
Remove ASImageNode thread affinity asserts (#57).
Improve ASRangeController dealloc-safety.

(1) We can't size nodes without a delegate, and if our owning controller
has been deallocated, our delegate will be nil.  Handle this more
gracefully.

(2) Our teardown code needs to be executed on the main thread, but it's
conceivable that we might hit refcount 0 on a background queue.  Force
deallocation to occur on the main thread.

Fix #67
1.0.1.
Added tintColor convenience methods

tintColor is now forwarded to the underlying view, and much more importantly, the node is notified when the tintColor changes on the view.

Fix text highlighting in UIScrollView

Highlight target layers with non-zero bounds.origin exhibited broken
text highlighting behavior. Highlights would appear offset by the
layer’s bounds.origin, and would not align with their target text. This
most often appeared in UIScrollView, where highlights would appear
incorrectly offset once the scroll view was scrolled. Fix by accounting
for bounds.origin in the calculations of the text overlay highlight
rects.
Add point parameter to ASTextNode delegate methods

Outfit ASTextNodeDelegate shouldHighlight and shouldLongPress methods
with a point parameter that describes the location of the relevant
touch.
