CodeSnip Old Code (SVN)

* 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.

Replaced "private" class visibility specifiers with "strict private"

* Changed syntax highlighters to return highlighted code in TEncodedData instead of string. Various encodings are used: RTF uses ASCII, HTML uses UTF8 and nul uses Unicode.
* Made minimum possible changes to affected units - simply convert encoded data back to strings. (Later we'll need to change this).

Development branch for CodeSnip release 4.

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