CodeSnip Old Code (SVN)

* Removed code that set size of body panel from THTMLViewDlg: this process should take place in an ArrangeForm method, not from ConfigForm as was the case here. All THTMLViewDlg does now is load HTML content via an abstract method call.
* Modified all descendant classes re changes in THTMLViewDlg: each class now sets body panel size in an ArrangeForm method.

Changed value of view link modal result. Fixes bug #2947794 .

Changed form classes to prevent public construction - forms must be displayed via class methods, not by directly constructing object. Added INoPublicConstruct to type definitions of forms and changed class methods that construct forms to call InternalCreate protected constructor instead of Create. Core logic to determine constructor behaviour is inherited from TBaseForm.

Added facility to render and display REML code entered in the Extra Information tab of the snippets editor:
* New dialog box to displayed the rendered code as HTML.
* A button added to snippets editor to validate the entered code, compile it and then display it in the new dialog box.
* Change log removed from snippets editor unit (FmUserDBEdit).
