CodeSnip Old Code (SVN)

Removed unnecessary TProtocolClass cast when reading list: no longer required now generic list being used.

* Simplified some code.
* Replaced FreeAndNil with .Free.
* Minor changes to comments.

XMLDoc commented unit.

Refactoring:
* Moved TProtocolClass into TProtocolFactory as a private type.
* Changed register from TClassList to TList<TProtocolClass>.
* Changed to use enumerator if TList<> and removed custom enumerator object.
* Added class constructor and destructor to TProtocolFactory to create and destroy registrar object. Adapted code accordingly.

Development branch for CodeSnip release 4.

Initial source is a copy of v3.8.4 (r1075).
