CodeSnip Old Code (SVN)

Removed temporary Category (ID) property from TSnippetBase and all code that supported using the property.
Updated affected code by removing all references to category IDs.

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.

Various snippet related interfaces, classes and methods renamed.

Added temporary Category property to TSnippetBase and removed property from TSnippet since it now inherits the property from TSnippetBase.

Added new IStringList.IsEmpty method and its implementation in TIStringList.
Modified all code that tested IStringList.Count against zero to use IStringList.IsEmpty intead.

Changed ISnippetIDList.Add from a function to a procedure.
Also changed so that an attempt to add the same snippet ID twice is silently ignored: this ensures the list acts like a set.

Added assertion to TSnippetIDList.IsEqual to ensure parameter is assigned.

Removed unused unit reference to USnippetIDs.

Copied TSnippetIDList class from USnippetIDs.
