CodeSnip Old Code (SVN)

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.

Reimplemented TTagGrouping.Populate method to create a grouping for every tag known to database as well as special "no tags" grouping.

Renamed TSnippetList defined in DB.USnippets unit as _TSnippetList and modified affect code accordingly. This is a first step towards changing snippet lists throughout the code to use a different list type.
