CodeSnip Old Code (SVN)

Refactoring:
* Renamed numerous identifiers that refer to "routine" with those that refer to "snippets" where appropriate.
* Updated calling code where required.

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.

Tidied up unit and changed to XMLDoc commenting.

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

Fixed bug in code that provides dialog box title.

Extracted common functionality from TSaveSnippetMgr and TSaveUnitMgr into new common base class, TSaveSourceMgr.

* Added combo box to display and select required file encoding in Save Source code dialog box. Required revision of dialog box template in resources to make room for new controls.
* Created code to supply supported encodings for each file type and to save files using required encoding to source file output manager and related code.
* Much XMLDoc commenting.

* Refactored TSourceFileInfo to store and expose file type related data via a record of type TSourceFileTypeInfo rather than using separate array properties for file extension and description (display name).
* Updated using units to use new interface to TSourceFileInfo.
* Changed commenting of USourceFileInfo unit to XMLDoc style.

Changed ownership of TSourceFileInfo objects. Formerly TSourceFileOutputMgr owned the object and save manager object filled in info via property. Now save manager objects own set up complete object's properties and pass to TSourceFileOutputMgr via constructor.

* Heavily revised UView unit once more to make views interfaced based.
* Updated using units re changes.
* Replaced many FreeAndNil calls with calls to .Free method.
