CodeSnip Old Code (SVN)

* 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).

* Added new IHiliteAttrs.ResetDefaultFont method and implemented in THiliteAttrs.
* Updated THiliteAttrsFactory.CreatePrintAttrs to use new method.

Removed the ISyntaxHiliter.Hilite method overload that read source and wrote highlighted source using streams. Also removed it from interface implementations, refactoring code as required.

Development branch for CodeSnip release 4.

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