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).

Changed TRTFBuilder to generate code as TRTF instead of ASCIIString. Modified using units accordingly.

* Added new TRTF and TRichEditHelper records and ERTF exception to URTFUtils unit.
* Methods of TRichEditHelper replaced and improved upon routines that helped with load, save and insert operations on rich edit controls. The routines were deleted.
* Updated all units that used the deleted routines to use TRichEditHelper instead.

* Corrected URTFUtils unit's RTFMakeSafeText routine to convert Unicode text to correct code page before writing it. Also corrected bug in code that generated Unicode characters.
* Updated TRTFBuilder to take code page parameter to constructor and to use it when writing code page to document and when writing text. Updated TRTFDocProperties similarly.
* Modified all using units to pass code page to TRTFBuilder constructor.

Development branch for CodeSnip release 4.
