CodeSnip Old Code (SVN)

Converted all classes etc. in UDetailPageHTML.pas and USnippetPageHTML.pas that use snippets, along with TSnippetHTML in USnippetHTML.pas, to use ISnippet to represent snippets instead of TSnippet.

Changed ISnippetView to have a SnippetID property of type TSnippetID instead of a Snippet property of type TSnippet.
Modified calling code accordingly.

Added some TODOs

Changed code that accessed _Database.SnippetCount to use Database.SnippetCount instead.
Deleted SnippetCount 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.

Removed support for ICategoryView from TDetailPageHTML and removed the now unused TCategoryPageHTML class.

Modified TTagsPageHTML to take account of possible null tag which is used to indicate a list of snippets with no tag.

Added support for HTML page that displays a list of snippets that have a certain tag.

Renamed various interface, class and factory method names in UView.pas to correct the spelling of "Null" in their names.
Modified affected code accordingly.

Renamed IDatabase and Database function, along with internal TDatabase class and PvtDatabase varibale by placing underscore in front of their names. This is to flag the items as "legacy" and to avoid name clashes with new database code being developed.
Modified all code that calls Database to use _Database instead.
