CodeSnip Old Code (SVN)

* Modified TDatabaseIniFile and TIniDataReader to handle encoding of database files correctly: they now support legacy default encoding and new UTF-8 encoding. Did this by using bew TMainDBFileReader class to do all file loading.
* Reorganised TDatabaseIniFile so that an internal stream is no longer used: all content from files through to loading of ini file is now processed in an IStringList. This avoids constantly encoding / decoding the text stream.
* Converted some of documentation to XMLDoc format.

* Added support for reading data files with ".4" extension interposed between file name and extension.
* Updated ini data file format documentation accordingly. Also noted the DelphiXE compilation result value.

Development branch for CodeSnip release 4.

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