CodeSnip Old Code (SVN)

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.

Changed XRefs search to use TSnippetID and ISnippetIDList types in preference to TSnippet and TSnippetList wherever possible.
Also changed TSearchFilterFactory.CreateXRefSearchFilter to take a TSnippetID parameter instead of a TSnippet. Modified calling code accordingly.

Added new GetDependentsOf and GetReferrersTo methods to IDatabase and implementation in _TDatabase.

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

Fixed bug in code that creates a tag for every category loaded from (old style) database file.

Added new GetAllTags method to IDatabase and its implementation in _TDatabase.

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.

Removed redundant TSnippet destructor.

Pushed IsEqual method down from TSnippet into TDBSnippet.

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