CodeSnip Old Code (SVN)

Merged trunk changes for release 3.8.9 (i.e. r1303 to r1305, r1307 to r1316) into the v4-dev branch.

Resolved conflicts:
* missing Doc/Design/ConfigFileStructure.odt and Doc/Design/IniDataFileForma.odt in v4-dev is correct - documents have been replaced by HTML docs in Docs/FileFormats directory.
* Docs/ReadMe.txt: used v4-dev changes where conflicted but kept typo fix from trunk.
* VCodeSnip.vi: kept version information from v4-dev but accepted updated copyright date in license block from trunk.

Some files are physically unchanged and have changes only to their svn:mergeinfo property.

* 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.

Development branch for CodeSnip release 4.

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