RFR: 6712: Make agent retransform classes when loaded dynamically

[Jessye Coleman-Shapiro]

This patch makes the Agent retransform all classes stored in the registry after it is loaded, when it is loaded dynamically.  Previously the transformations specified in the xml file path argument were not always being performed in this dynamic case.

Let me know what you think.
