CodeSnip Old Code (SVN)

Fixed long standing bug that was crashing when database was updated or restored after editing, adding or deleting any user defined snippet. Did this by storing an IViewKey object instead of an IView object. Problem with IView object is that the instances stored in treeview (and more particularly instances of any objects wrapped by the IView object) may change between when tree state is saved and when restored, causing a GPF or similar.

NOTE: This is a different fix to the one applied to the v3 code base.

* Heavily revised UView unit once more to make views interfaced based.
* Updated using units re changes.
* Replaced many FreeAndNil calls with calls to .Free method.

Heavily revised UView unit
* Replaced flexible and "smelly" single TViewItem class that handled all view types with heirachy of classes for each view type.
* Added factory class.
* Updated using units re changes.

Development branch for CodeSnip release 4.

Initial source is a copy of v3.8.4 (r1075).
