This patch aims to clean up and improve the
ObjectAccess class which currently does a
*lot* of unnecessary operations, but is intended
for use in many places especially with repeated
use. Therefore, any even small optimisation in
this class would be a benefit.

* Uses more native PHP methods where reasonable
* Uses fewer method calls where reasonable
* Gets rid of a variable passed by reference
* More cases return NULL rather than throw Exceptions
* Fastest decisions and access methods come first
* Reflection-based access isolated to edge cases and
  access with the "force" flag being TRUE.
* Sacrifices ability to read objects of types other
  than persisted objects contained in an ObjectStorage
  or subclass of ObjectStorage.
* Changes verdict from FALSE to TRUE when determining
  if a dynamically added property exists on an object
  (these are, by definition, publicly accessible).
