* More unstripping fixes. Explorer now works 100% on a blank Unity project (so should therefore work on any Unity game, regardless of stripping).
* Some cleanups
* Added support for viewing Texture2D (and Sprite) from the Inspector, and exporting them to PNG
* Fixed an issue with generic methods not showing their return value type
* Fixed an issue where destroyed UnityEngine.Objects would cause issues in the inspector
* Fixed an issue when caching a ValueCollection of a Dictionary (the generic argument for the Entry Type is the last arg, not the first as with other Enumerables)
