CodeSnip Old Code (SVN)

* Changed TPreviewDlg box so that required document type is passed to Execute method. No longer detects doc type by examining file.
* Modified units that use TPreviewDlg to pass new required parameter.
* XMLDoc commented FmPreviewDlg unit.

* Changed preview dialog box and IPreview interface to accept doc content as TEncodedData rather than a string.
* Changed all implementations of IPreview accordingly.
* Also updated affected using units.

* 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 how document titles are handled - reduced complexity. Preview dialog box now supplied with title rather than having to get it from document where possible. Unit titles no longer include file name - this could be in error in preview dialog box.

Renamed USourceFileOutputMgr unit as USaveSourceMgr and updated all using units accordingly.
