CodeSnip Old Code (SVN)

* Refactored, renamed and moved some code.
* Fixed some errors that could lead to attempts to copy files or directories to other with the same name.
* A lot of re-commenting.

Bumped per-user config file version to 8 and common config file version to 6. Files are now stamped with these version numbers.

Revised install script and associated Pascal Script files to work with new directory and file names used for CodeSnip 4.

Rising complexity in working with complex relationship between various file versions led to so significant refactoring of the code, particularly that that records the various paths and file names and detects previous installed versions. This enabled simplification of ini and database update code.

Updated install script to create any new user.4.ini file (and any missing Common.ini file as Unicode. Added new Unicode.ps support script to assist with this.

Updated installer scripts to recognise and copy config files and databases from former locations to work with new v4 user config file and database directory names.

Development branch for CodeSnip release 4.

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