Unity 4.6.1

What's new in this version:

Features:
- WebPlayer: Added support for 64 bit Mac OS X browsers.

Improvements:
- AssetBundles: Added additional information about WWW.LoadFromCacheOrDownload.
- Graphics: Improved performance when allocating memory for large numbers of temporary objects.
- Graphics: Optimized culling of lights in a mostly deferred scene with a few forward-rendered objects.
- Physics 2D: Added 'Static Collider Shapes' to profiler for 2D physics.
- Physics 2D: Renamed Physics2D.deleteStopsCallbacks to Physics.changeStopsCallbacks to better represent its purpose (old property is now obsolete).
- Serialization: Randomize fileIDs for objects in prefabs to lower the chance of merge conflicts.
- UI: Encapsulate children mesh bounds when calculating Root Bounds. Also cache the value so we don't calculate every time we draw.
