Tools library for unity3d: auto caching for transform property

Common.MonoBehaviourBase class provides 2 optimizations for access to component transform:

• Standard "transform" property 2-2.5x faster than with standard component.
• Internal _cachedTransform field for all inherited classes with additional 2x performance boost relative to already boosted "transform" property.
