CodeSnip Old Code (SVN)

Modified objects that read and write main and user databases, including nul reader used when one of the databases doesn't exist:
* Removed code that registered reader / writer - now redundant.
* Moved class declarations from implementation to interface sections of unit.
* Except for nul reader, removed references and dependencies on deleted TDatabaseType. Additionally, path to database directory now passed in constructor rather than being determined within read class.

Removed change logs.

Added svn:keywords property with Rev and Date keywords.

Incremented user database and export file format to v4 to accommodate updated REML code used in snippets Extra property. v3 format still used if updated REML code is not needed.

Imported CodeSnip v3.0
