CodeSnip Old Code (SVN)

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.

Renamed IReadOnlySnippet as ISnippet and made required changes to affected code.
Also renamed TDatabase's LookupReadOnlySnippet method and LookupSnippet.

Corrected spelling error in method name.

Various snippet related interfaces, classes and methods renamed.

Pushed IsEqual method down from TSnippet into TDBSnippet.

Added new IsEmpty method TDBSnippetsTable.

Removed TSnippetID.TComparer and TSnippetID.TEqualityComparer and replaced with single TSnippetID.TComparator class.
Made consequent changes to using code.

Changed TDBSnippetsTable.Update to update required snippet in place rather than storing a new instance and deleting old one.

Made minimal changes to enable unit to compile in "parsnip".

Copied CS.Database.Core.SnippetsTable.pas from "experimental" branch and added to project as Main/CS.Database.SnippetsTable.pas.
