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 clone constructor to TEncodedData.
* Modified TEncodedData's constructors to ensure data is always a copy of data passed to constructor, not just a reference.

Renamed TEncodingType.etUTF16 as etUnicode.

Updated svn:mergeinfo properties modified by last merge from trunk of r1257. There were no physical changes to the files.

Merged bug fix from trunk r1257.

Bug fix: compile results no longer listed for freeform snippets.

* Renamed TRoutinePrintDocument as TSnippetPrintDocument and renamed various fields and parameters similarly.
* Updated using UPrintMgr unit accordingly.

Updated print engine, print manager and unit containing print documents to use TRTF to contain documents instead of TStream.

Included a temporary fix in TRoutinePrintDocument to work with streams still produced by TRTFRoutineDoc.

* Changed TSourcePrefsFrame to always use default highlighter font in preview.
* Fixed display bug where source preferences preview pane was to small to display all samples.
* Changed TSourcePrefsPreview to return TRTF containing generated RTF code.

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