CodeSnip Old Code (SVN)

Added new UCategoryListAdapter unit that implements a class designed for use with GUI controls that adapts a list of snippet categories by providing an alternative interface to the list, sorted by description.

Moved FloatToInt routine from URTFBuilder.pas into UUtils.pas.

Replaced use of TList in TRTFColourTable with TIntegerList to maintain list of colours.

Commented the TAlphaGrouping.LetterCompare method.

Modified to use TObjectListEx from ULists unit instead of the VCL's TObjectList.

Reimplemented tree view building code to use TGrouping and TGroupItem classes and descendant classes to group snippets as required before creating the required tree views.

Added new classes:
* TObjectListEnum - enumerator for various object lists
* TObjectListEx - an enhanced TObjectList with new enumerator and additional helper methods.
* TSortedObjectList - maintains a sorted list of objects using a provided TObjectCompare comparison method.
* TSortedObjectDictionary - a dictionary mapping key objects onto value objects which maintains a sorted list of keys using a provided TObjectCompare method.
Also modified TIntegerList to use TObjectListEx instead of TObjectList.

Added new UGroups unit that defines classes that group snippets together in different ways.

Corrected error in TSnippets.RemoveChangeEventHandler: code was *adding* the event handler rather than removing it.

Added reference to FrSelectSnippetsBase frame that now contains base class for snippet selection frame.
