* Revised TRoutineList and TCategoryList to use Delphi's TObjectList<> object instead of project's TObjectListEx to implement list of snippets and categories respectively.
* Removed TRoutineList's and TCategoryList's private TEnumerator class. We now use enumerator provided by TObjectList<>.

Completely rewrote TViewItemList as a class that descends from TList<TViewItem> and simply overrides constructor. The class formerly owned and used a TObjectListEx instance to maintain list and exposed relevant properties.

* Revised TConstAndTypeList to use Delphi's TObjectList<> object instead of project's TObjectListEx to implement list of constant and type snippets.
* Removed TConstAndTypeList's private TEnumerator class. We now use enumerator provided by TObjectList<>.
* Replaced various calls to FreeAndNil with direct call to objects' Free methods.

* Revised TSnippetIDList to use Delphi's TList<> object instead of project's TObjectListEx to implement snippet id list.
* Removed TSnippetIDList.TSnippetIDWrapper class. This had been used to wrap TSnippetID record in an object for inclusion in a TObjectListEx. The class is no longer needed because TList<> can directly handle TSnippetID records.
* Replaced call to FreeAndNil with direct call to object's Free method.

* Revised TOverviewTreeState to use Delphi's TObjectList<> object instead of project's TObjectListEx to implement list section state objects.
* Replaced various calls to FreeAndNil with direct call to objects' Free methods.

* Refactored TNews to use Delphi's TObjectList<> object instead of project's TObjectListEx to implement list of news items.
* Removed TNews' private TEnumerator class. We now use enumerator provided by TObjectList<>.
* Replaced various calls to FreeAndNil with direct call to objects' Free methods.

* Replaced call to FreeAndNil with direct call to object's Free method.

* Removed now unused TIntegerList class.
* Replaced calls to FreeAndNil with direct calls to objects' Free methods.

Refactored TWBPopupMenuMgr to use TDictionary object instead of TIntegerList for map of command bar ids to popup menu components.

* Replaced use of TIntegerList to maintain a list of colours in colour table in TRTFColourTable with TList<TColor>.
