CodeSnip Old Code (SVN)

Replaced calls to TSnippetKindInfoList to get list of available snippet kinds with calls to Database.GetAllSnippetKinds and methods of the returned ISnippetKindList object.

Changed classes in UGroups unit to use ISnippet instead of TSnippet for all references to snippet objects, including the the public TGroupItem.SnippetList property.
Changed code in units that use TGroupItem.SnippetList re the change of snippet type.

Removed unused unit references.

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.

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

Changed code that accessed _Database.Select to use Database.SelectSnippets instead.
Deleted Select method from IDatabase and _TDatabase.

Changed code that accessed _Database.GetAllTags to use Database.GetAllTags instead.
Deleted GetAllTags method from IDatabase and _TDatabase.

Changed code that accessed _Database.SelectAll to use Database.GetAllSnippets instead.
Deleted SelectAll method from IDatabase and _TDatabase.

Extracted nested TTitleComparer and TTitleEqualityComparer from within TSnippet and made classes in their own right, named TSnippetTitleComparer and TSnippetTitleEqualityComparer.
Modified using code re this renaming.

Fixed error in TTagGrouping.Populate that was failing to filter grouped snippets using given master snippet ID list, meaning that all snippets were always displayed, even when only a the snippets matching a search should be displayed.
