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 ISearchFilter.Match to take a TSnippetID parameter instead of a TSnippet.
Changed ISearch.Execute's input and output parameters types from TSnippetList to ISnippetIDList.
Made minimal internal changes necessitated by these type changes.

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.

Made minimal modification to calling code in TMainDisplayMgr re these changes.

Changed type of internal snippet list from TSnippetList to ISnippetIDList.

Added IsEqual method to ISnippetIDList and implemented it in TSnippetIDList.

Added TSnippetList.ToIDList helper method to convert snippet list to ID list. This is to help transition from TSnippetList to ISnippetIDList.
Replaced custom "fudged" code in FrOverview and UDialogMgr units with call to new ToIDList.
