CodeSnip Old Code (SVN)

Added MPL 2.0 header comment.

Added new unit to project containing IDatabaseLoader interface to be supported by all database loader classes.

Added new ReadBytes method to TFileIO to read a specified number of bytes from a file.
Some other changes to support ReadBytes.

Added new TryLookupSnippet and TryLookupEditableSnippet methods to TDatabase.

Removed unused internal type.

Moved TDBSnippetProp type from CS.Database.Type unit to CS.Database.IO.Native unit.
Deleted TDBSnippetProps set type from CS.Database.Type.

Removed TDBSnippetProps parameter from TDatabase.LookupSnippet method.

Changed TDatabase.SelectSnippets to take a simple function reference as its parameter instead of IDBFilter instance.
Modified calling code accordingly.
Removed now-redundant IDBFilter interface and implementations in TDBFilter and TDelegatedDBFilter.

Added TODO / note re how to handle any performance issues re cloning of snippets on each lookup.

Removed facility to specify fields needed when getting read only snippet: now all read only snippets have full compliment of fields.

NOTE: I've done this because being able select fields was potentially a way of introducing bugs, especially when it isn't easy to track how a read only snippet is used.
