CodeSnip Old Code (SVN)

* Made TSyntaxHiliter public.
* Removed temporary CreateRenderedHiliter function that constructed TSyntaxHiliter instances.
* Updated code that user CreateRenderedHiliter to construct TSyntaxHiliter directly.

Flattened highlighter class heirachy into a single class that takes a renderer object to do highlighting. Named this class TSyntaxHiliter, made it sealed and change visibility of methods and fields.

Reimplemented TNulDocumentHiliter to return document text directly instead of using TNulHiliter. Then removed now redundant TNulHiliter class.

Removed redundant TSyntaxHiliterFactory enumeration, TSyntaxHiliterClass class ref, and TBaseHTMLHiliter and all descendant highlighter classes.

* Modified TSnippetHTML.HiliteSource to use TRenderedHiliter and suitable renderer to highlight detail frame's source code.
* Added temporary function to Hiliter.UHiliters to enable TRenderedHiliter object to be instantiated.

* Added new highlight renderer interface and objects to render syntax highlighted source code.
* Added new descendant of TSyntaxHiliter that passes off rendering to new renderer objects.
* Added new static classes to generate complete RTF and HTML (and plain text) documents using new renderers.
* Modified all using code that produces whole documents (rather than fragments) to use the new static classes.
* Simplified some code as a result.

Refactored out the now empty TActiveTextElem base class.

* Removed akText value from TActiveTextElemKind and renamed enumeration as TActiveTextActionElemKind.
* Moved Kind property from IActiveTextElem interface into IActiveTextActionElem and modified implementation of interfaces accordingly.
* Updated all using code re these changes.

Removed left over debug code.
