CodeSnip Old Code (SVN)

Removed redundant DB.UCategory unit reference.

Removed redundant GetCatSelection method from IQuery and TQuery.

Added IQuery.FilterSelection method, and its implementation in TQuery, that takes a filter function and returns the result of applying the filter to the current selection.

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.

Removed unused USnippetIDs unit from project.
Changed affected units to use CS.Database.Snippets instead.

Changed data structure that maintains list of selected snippets from TSnippetList to ISnippetIDList and made necessary changes to affected code.
Modified code that calls ISearch.Execute re changes made in USearch unit at revision 3980.

Changed IQuery.Selection property and its associated getter function to return a ISnippetIDList object instead of a TSnippetList.
Provided a minimal implementation of those changes in TQuery: further work needed to rationalise the change.
Modified code that uses IQuery.Selection as necessary.

Changed IQuery.GetCatSelection and implementation to return a ISnippetIDList instead of populating a given TSnippetList.
Modified code in TSnippetSourceGen that uses IQuery.GetCatSelection accordingly.

Renamed TCategory.Snippets property as SnippetIDs and changed its type to ISnippetIDList.
Made appropriate changes to affected code.

Renamed IDatabase's Snippets property as _Snippets as a first step in elimination of the property.
